Hey, how do I set the last day of the month to be executed on time?

Hey, how do I set the last day of the month to be executed on time?

Did you find any way to do it?

[JohnRoesler]

It doesn't look like there is a way to do that currently. Seems like a feature would need to be added. Perhaps a Monthly() option that allows for things like FirstDay(), LastDay(), DayOfMonth(15).

Yes, currently he needs FirstDay(), LastDay(), DayOfMonth(15)

I'm not certain this is the purview of gocron.

For example, I've needed to create a report on the 12th of each month - EXCEPT if the 12th was on the weekend and then it was either the 11th if the 12th was a Saturday or the 13th if the 12th was a Sunday. That would be an interesting set of options to describe in a single line of gocron scheduling.

So, maybe something like this for the question at hand

 func coreTask() {
     fmt.Println("Must be last day of month - time to make the donuts")
 }
 
 func task() {
     now := time.Now()
     currentYear, currentMonth, currentDay := now.Date()
     currentLocation := now.Location()
 
     firstOfMonth := time.Date(currentYear, currentMonth, 1, 0, 0, 0, 0, currentLocation)
     lastOfMonth := firstOfMonth.AddDate(0, 1, -1)
     if lastOfMonth.Day() == currentDay {
         coreTask()
     }
}

gocron.Every(1).Day().At("10:30").Do(task)

Last day of month code from here

I like your solution @wishdev! Seems very reasonable to handle outside of gocron as to your point - the options could be highly involved getting exactly the right cron schedule unless it was a simple, I want this date of the month always, or the first day or last day.

Nice solution @wishdev. Was also looking for something similar and this does the job. Good enough for me 👍

[JohnRoesler]

@003random come check out our active fork https://github.com/go-co-op/gocron we’ve added support for Monthly schedules 👍

Oh awesome! Thanks @JohnRoesler
