Calendar and locale

toCalendar

default: persian

available option: persian gregorian

from version 1.0.* persianDate have an option that allows developers to set calendar type of Date object.

you can change calendar type globally or only in specific object

if you want change calendar type globally:

persianDate.toCalendar('gregorian');
new persianDate([2017]).year(); // 2017
new persianDate([2017]).format('MMM'); // "ژانویه"

or only on instance:

new persianDate([1396]).toCalendar('gregorian').year(); // 2017

toLeapYearMode

default: algorithmic

available option: algorithmic, astronomical

There is two popular way to determining leap years for the Persian calendar.

astronomical: occur whenever that number of days elapsed between equinoxes at the reference meridian.
algorithmic: based on Behrooz-Birashk proposed algorithm.

After version 1.0.* persianDate support both algorithms and you can choose which algorithm use in your project. currently, we have support 2 type of leap year mode algorithmic, astronomical.

you can change it globally like this example

persianDate.toLeapYearMode('algorithmic')

or change it in you instance

new persianDate().toLeapYearMode('algorithmic')

toLeapYearMode only work when calendar type is persian, and doesnt any effect on gregorian calendar

toLocale

default: fa

available option: fa en

if you want change locale globally:

persianDate.toLocale('fa');
new persianDate([1396,6,17]).format(); // "۱۳۹۶-۰۶-۱۷ ۰۰:۰۰:۰۰ ق ظ"
new persianDate([1396,6,17]).format('dddd'); // "جمعه"
new persianDate([1396,6,17]).format('MMMM'); // "شهریور"

persianDate.toLocale('en');
new persianDate([1396,6,17]).format(); // "1396-06-17 00:00:00 AM"
new persianDate([1396,6,17]).format('dddd'); // "Friday"
new persianDate([1396,6,17]).format('MMMM'); // "Shahrivar"

or only on instance:

new persianDate([1396,6,17]).toLocale('fa').format(); // "۱۳۹۶-۰۶-۱۷ ۰۰:۰۰:۰۰ ق ظ"
new persianDate([1396,6,17]).toLocale('fa').format('dddd'); // "جمعه"
new persianDate([1396,6,17]).toLocale('fa').format('MMMM'); // "شهریور"

persianDate.toCalendar('gregorian');
new persianDate([1396,6,17]).toLocale('en').format(); // "1397-07-07 00:00:00 AM"
new persianDate([1396,6,17]).toLocale('en').format('dddd'); // "Friday"
new persianDate([1396,6,17]).toLocale('en').format('MMMM'); // "June"

after version 1.0.*, you must use toLocale instead formatPersian, for show persian or english digit.

Parse

Instead of modifying the native Date.prototype , persianDate creates a wrapper for the Date object. To get this wrapper object, simply call persianDate() with one of the supported input types.

Now

new persianDate();

To get the current date and time, just call persianDate() with no parameters.

var now = new persianDate();

This is essentially the same as calling new persianDate(new Date()) .

Unix Offset (milliseconds)

new persianDate(/* Number */);

Similar to new Date(Number), you can create a persianDate by passing an integer value representing the number of milliseconds since the Unix Epoch (Jan 1 1970 12AM UTC).

var day = new persianDate(1318781876406); // "۱۳۹۰-۰۷-۲۴ ۱۹:۴۷:۵۶ ب ظ"

Unix Timestamp (seconds)

persianDate.unix(/* Number */);

To create a persianDate from a Unix timestamp (seconds since the Unix Epoch), use persianDate.unix(Number)

var day = new persianDate.unix(1318781876); // "۱۳۹۰-۰۷-۲۴ ۱۹:۴۷:۵۶ ب ظ"

This is implemented as persianDate(timestamp * 1000) , so partial seconds in the input timestamp are included.

Date

new persianDate(new Date());

You can create a persianDate with a pre-existing native Javascript Date object.

var day = new Date(2011, 9, 16);
var dayWrapper = new persianDate(day); // "۱۳۹۰-۰۷-۲۴ ۰۰:۰۰:۰۰ ق ظ"

This is the fastest way to get a persianDate.js wrapper.

Array

['year', 'month', 'day', 'hour', 'minute', 'second', 'millisecond']

new persianDate([1391, 12, 29, 12, 25, 25, 900]);

You can create a persianDate with an array of numbers that mirror the parameters passed to new Date() But As Persian Date Number Like [1393,2,22,11,22,30]

new persianDate([1393, 1, 14, 15,25, 50,125]); // "۱۳۹۳-۰۱-۱۴ ۱۵:۲۵:۵۰ ب ظ"

Any value past the year is optional, and will default to the lowest possible number.

new persianDate([1392]); // Farvardin 1st
new persianDate([1392, 6]); // Shahrivar 1st
new persianDate([1392, 6, 10]); // Shahrivar 10th

Note: from 1.0.* you can pass gregorian date array to create gregorian date object. for this functionality you must change date object calendar type by toCalendar('gregorian')

example:

persianDate.toCalendar('gregorian');
new persianDate([2017,2,2]).format(); // "۲۰۱۷-۰۲-۰۲ ۰۰:۰۰:۰۰ ق ظ"

ASP.NET JSON Date

new persianDate(String);

ASP.NET returns dates in JSON as /Date(1198908717056)/ or /Date(1198908717056-0700)/

If a string that matches this format is passed in, it will be parsed correctly.

new persianDate("/Date(1198908717056-0700)/"); //"۱۳۸۶-۱۰-۰۸ ۰۹:۴۱:۵۷ ق ظ"

PesianDate Clone

new persianDate(persianDate);

All persianDate are mutable. If you want a clone of a persianDate, you can do so explicitly or implicitly. Calling persianDate() on a persianDate will clone it.

var a = new persianDate([1392]);
var b = new persianDate(a);
a.year(1300);
b.year(); // 1392

var a = new persianDate([1392]);
var b = a.clone();
a.year(1300);
b.year(); // 1392

Get + Set

persainDate.js uses overloaded getters and setters. You may be familiar with this pattern from it's use in jQuery.

Calling these methods without parameters acts as a getter, and calling them with a parameter acts as a setter.

These map to the corresponding function on the native Date object.

new persianDate().seconds(30).valueOf() === new Date().setSeconds(30); // true
new persianDate().seconds() === new Date().getSeconds(); // true

Millisecond

new persianDate().millisecond(100);
new persianDate().millisecond(); // 100
new persianDate().milliseconds(100);
new persianDate().milliseconds(); // 100

Gets or sets the milliseconds.

Accepts numbers from 0 to 999. If the range is exceeded, it will bubble up to the seconds.

Second

new persianDate().second(10);
new persianDate().second(); // 10
new persianDate().seconds(10);
new persianDate().seconds(); // 10

Gets or sets the seconds.

Accepts numbers from 0 to 59. If the range is exceeded, it will bubble up to the minutes.

Minute

new persianDate().minute(20);
new persianDate().minute(); // 20
new persianDate().minutes(20);
new persianDate().minutes(); // 20

Gets or sets the minutes.

Accepts numbers from 0 to 59. If the range is exceeded, it will bubble up to the hours.

Hour

new persianDate().hour(12);
new persianDate().hour(); // 12
new persianDate().hours(12);
new persianDate().hours(); // 12

Gets or sets the hour.

Accepts numbers from 0 to 23. If the range is exceeded, it will bubble up to the day.

Date of Month

new persianDate().date(23);
new persianDate().date(); // 23
new persianDate().dates(23);
new persianDate().dates(); // 23

Gets or sets the day of the month.

Accepts numbers from 1 to 31. If the range is exceeded, it will bubble up to the months.

Note: persianDate#date is for the date of the month, and persianDate#day is for the day of the week.

Year

new persianDate().year(1390);
new persianDate().year(); // 1390
new persianDate().years(1390);
new persianDate().years(); // 1390

Gets or sets the year.

Accepts numbers from -270,000 to 270,000.

Day of Week

new persianDate().day(); // Number
new persianDate().days(); // Number

Gets the day of the week.

Note: persianDate#date is for the date of the month, and persianDate#day is for the day of the week.

Manipulate

Once you have a PersianDate , you may want to manipulate it in some way. There are a number of methods to help with this.

persianDate.js uses the fluent interface pattern, also known as method chaining. This allows you to do crazy things like the following.

new persianDate().add('days', 7).subtract('months', 1).year(2009).hours(0).minutes(0).seconds(0);

Note: It should be noted that persianDates are mutable. Calling any of the manipulation methods will change the original persianDate.

If you want to create a copy and manipulate it, you should use persianDate#clone before manipulating the persianDate.

Add

new persianDate().add(String, Number);

Mutates the original persianDate by adding time.

This is a pretty robust function for adding time to an existing persianDate. To add time, pass the key of what time you want to add, and the amount you want to add.

new persianDate().add('days', 7);

There are some shorthand keys as well if you're into that whole brevity thing.

new persianDate().add('d', 7);

Key	Alternate	Shorthand
years	year	y
months	month	M
weeks	week	w
days	day	d
hours	hour	h
minutes	minute	m
seconds	second	s
milliseconds	millisecond	ms

If you want to add multiple different keys at the same time, you can pass them in as an object literal.

new persianDate().add('days', 7).add('months', 1); // with chaining

There are no upper limits for the amounts, so you can overload any of the parameters.

new persianDate().add('milliseconds', 1000000); // a million milliseconds
new persianDate().add('days', 360); // 360 days

Subtract

new persianDate().subtract(String, Number);

Mutates the original persianDate by subtracting time.

This is exactly the same as persianDate#add , only instead of adding time, it subtracts time.

new persianDate().subtract('days', 7);

Start of Time

new persianDate().startOf(String);

Mutates the original persianDate by setting it to the start of a unit of time.

new persianDate().startOf('year');   // set to Farvardin 1st, 12:00 am this year
new persianDate().startOf('month');  // set to the first of this month, 12:00 am
new persianDate().startOf('week');   // set to the first day of this week, 12:00 am
new persianDate().startOf('day');    // set to 12:00 am today
new persianDate().startOf('hour');   // set to now, but with 0 mins, 0 secs, and 0 ms
new persianDate().startOf('minute'); // set to now, but with 0 seconds and 0 milliseconds
new persianDate().startOf('second'); // same as persianDate().milliseconds(0);

These shortcuts are essentially the same as the following.

new persianDate().startOf('year');
new persianDate().month(1).date(1).hours(0).minutes(0).seconds(0).milliseconds(0);

new persianDate().startOf('hour');
new persianDate().minutes(0).seconds(0).milliseconds(0)

End of Time

new persianDate().endOf(String);

Mutates the original persianDate by setting it to the end of a unit of time.

This is the same as persianDate#startOf , only instead of setting to the start of a unit of time, it sets to the end of a unit of time.

new persianDate().endOf("year"); // set the persianDate to 12-31 11:59:59.999 pm this year

Display

Once parsing and manipulation are done, you need some way to display the persianDate.

Format

new persianDate().format();
new persianDate().format('string');

This is the most robust display option. It takes a string of tokens and replaces them with their corresponding values.

new persianDate().format("dddd, MMMM DD YYYY, h:mm:ss a"); // "شنبه, فروردین ۱۲ ۱۳۹۶, ۵:۵۴:۱۱ ب ظ"
new persianDate().format("dddd, ha"); // "شنبه, ۵ب ظ"

This is the most robust display option. It takes a string of tokens and replaces them with their corresponding values.

Default format

ISO8601 format YYYY-MM-DDTHH:mm:ssZ "۱۳۹۱-۱۰-۰۴ ۱۱:۲۷:۵۳ ق ظ"

Format To Persian digit

Deprecated as 1.0.* instead use toLocale

By Default persianDate format, use Persian Number System, for engilsh number Set formatPersian Option as false

var d = new persianDate([1391]);
d.format(); //"۱۳۹۱-۰۱-۰۱ ۰۰:۰۰:۰۰ ق ظ"
window.formatPersian = false;
d.format(); //"1391-01-01 00:00:00 AM"

Also you can set golbal config like this

window.formatPersian  = false;

Note: After Set Global config you can set config for every instance

var d = new persianDate([1391]);
d.format(); //"۱۳۹۱-۰۱-۰۱ ۰۰:۰۰:۰۰ ق ظ"
window.formatPersian = false;
d.format(); //"1391-01-01 00:00:00 AM"
d.formatPersian = true;
d.format(); //"۱۳۹۱-۰۱-۰۱ ۰۰:۰۰:۰۰ ق ظ"

Difference

new persianDate().diff(PersianDate|String|Boolean);

Accept 3 argument, (ccmparable persianDate object, difference key, boolean value that make returned output float)

To get the difference in milliseconds, use persianDate#diff.

var a = new persianDate([1392, 1, 29]);
var b = new persianDate([1392, 1, 28]);
a.diff(b) // 86400000

To get the difference in another unit of measurement, pass that measurement as the second argument.

var a = new persianDate([1392, 1, 29]);
var b = new persianDate([1392,1, 28]);
a.diff(b, 'days'); // 1

The supported measurements are years, months, weeks, days, hours, minutes, and seconds. For ease of development, the singular forms are supported .

var a = new persianDate([1391, 1]);
var b = new persianDate([1392, 5]);
a.diff(b, 'years');
a.diff(b, 'years', true);

If the persianDate is later than the persianDate you are passing to persianDate.fn.diff , the return value will be negative.

var a = new persianDate();
var b = new persianDate().add('seconds', 1);
a.diff(b); // -1000
b.diff(a); // 1000

A easy way to think of this is by replacing .diff( with a minus operator.

a.diff(b);
b.diff(a);

Unix Offset (milliseconds)

new persianDate().valueOf();

persianDate#valueOf simply outputs the number of milliseconds since the Unix Epoch, just like Date#valueOf .

new persianDate(1318874398806).valueOf(); // 1318874398806
new persianDate(1318874398806).format(); // "۱۳۹۰-۰۷-۲۵ ۲۱:۲۹:۵۸ ب ظ"

To get a Unix timestamp (the number of seconds since the epoch) from a persianDate , use persianDate#unix .

Unix Timestamp (seconds)

new persianDate().unix();

persianDate#unix outputs a Unix timestamp (the of seconds since the Unix Epoch).

new persianDate(1318874398806).unix(); // 1318874398

This value is floored to the nearest second, and does not include a milliseconds component.

Timezone Offset

new persianDate().zone();

Get the timezone offset in minutes.

new persianDate().zone(); // (60, 120, 240, -270, etc.)

Days in Month

new persianDate().daysInMonth();

Get the number of days in the current month.

new persianDate([1392,1]).daysInMonth(); // 31
new persianDate([1392,8]).daysInMonth(); // 30
new persianDate([1392,12]).daysInMonth(); // 29
new persianDate([1391,12]).daysInMonth(); // 30

As Javascript Date

new persianDate().toDate();

To get the native Date object that persianDate.js wraps, use persianDate#toDate .

This will return the Date that the persianDate uses.

As Array

new persianDate().toArray();

This returns an array that mirrors the parameters from new persianDate() .

new persianDate().toArray(); // [1391, 1, 4, 14, 40, 16, 154];

Range Name

Helper method that return date range name like week days name, month names, month days names (specially in persian calendar).

persianDate.toLocale('fa').toCalendar('persian');

persianDate.rangeName().weekdays;
// ["شنبه", "یکشنبه", "دوشنبه", "سه شنبه", "چهار شنبه", "پنج‌شنبه", "جمعه"]

persianDate.rangeName().weekdaysMin;
// ["ش", "ی", "د", "س", "چ", "پ", "ج"]

persianDate.rangeName().months;
// ["فروردین", "اردیبهشت", "خرداد", "تیر", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند"]

persianDate.rangeName().monthsShort; 
// ["فرو", "ارد", "خرد", "تیر", "مرد", "شهر", "مهر", "آبا", "آذر", "دی", "بهم", "اسف"]

persianDate.rangeName().persianDaysName[0]; 
// "اورمزد"

Persian month day name wiki

Also You can get Gregorian calendar range names

persianDate.toCalendar('gregorian').rangeName().months;
// ["ژانویه", "فوریه", "مارس", "آوریل", "مه", "ژوئن", "ژوئیه", "اوت", "سپتامبر", "اکتبر", "نوامبر", "دسامبر"]

persianDate.toCalendar('gregorian').toLocale('en').rangeName().months;
// ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]


persianDate.toCalendar('gregorian').toLocale('en').rangeName().weekDayes;
// ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday']

persianDate.toCalendar('gregorian').toLocale('en').rangeName().weekDayesShort;
// ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat']

persianDate.toCalendar('gregorian').toLocale('en').rangeName().weekDayesMin;
// ['Su', 'Mo', 'Tu', 'We', 'Th', 'Fr', 'Sa']

Query
