Showing weekday instead of hours in hourly forecast between 00:00 and 01:00

[hg1337]

Describe the bug
In the hourly chart, it shows the (same) weekday instead of the hour for each hour, but only between 00:00 and 01:00. Happens with multiple weather providers, e.g. the default met.no. Seems that the chart headers somehow think that it's a daily chart when the current (local) hour is 00.

To Reproduce
Steps to reproduce the behavior:

1. Add this chart to your dashbord:

type: custom:weather-chart-card
icons: /local/custom-lovelace/weather-chart-card/icons2/
entity: weather.home
show_main: false
show_temperature: false
show_current_condition: false
show_attributes: false
show_time: false
show_time_seconds: false
show_day: false
show_date: false
show_humidity: false
show_pressure: false
show_wind_direction: false
show_wind_speed: false
show_sun: false
show_feels_like: false
show_dew_point: false
show_wind_gust_speed: false
show_visibility: false
show_last_changed: false
use_12hour_format: false
icons_size: '32'
animated_icons: false
icon_style: style1
forecast:
  precipitation_type: rainfall
  show_probability: true
  labels_font_size: '11'
  precip_bar_size: '100'
  style: style1
  show_wind_forecast: true
  condition_icons: true
  round_temp: false
  type: hourly
  number_of_forecasts: '0'
  disable_animation: true
  chart_height: '150'
units:
  pressure: ''
  speed: ''

2. If it's between 01:00 and 23:59, everything looks normal.
3. Wait till after midnight. (Depending on when the data is updated might take a few minutes.)
4. Look at the chart, it shows weekdays instead of hours.

Expected behavior
Shows hours like the other 23 hours of the day.
