Day and night length
Each month in this plugin has a unique day and night length for extra realism. Just like in real life the days in summer are longer than the night and the opposite in winter. These are the default settings:
The day and night length can be changed to anything you want in the configuration. By anything I mean anything. It does not have to be a total of 20 minutes and there is no limit on how long a day can be. You could make the day 30 hours and the night 1 minute.
Increasing the day and night length in all months is also a great way to increase the length of the year while still having the same amount of days per month. January 60 doesn't look good. Simply setting the total day length to 40 minutes (day + night = 40) is a great way of doubling the length of each year.
