Hello there, I am creating a calendar for a sci-fi game I am creating for a roll20 session. I would appreicate some help in figuring out the current Month/Day/Year for this new calendar based on our Real World calendar date of 11/23/2645.

This new calendar is based on 11 months with 20 days (4 weeks of 5 days) with 23 hour days. It has no leap years. Year 1 of this new calendar is based on January 1st 2290 AD of our calendar. I would really appreciate some help figuring this out!

The main things I need help with is: Converting the extra hour per RL day into amount of days added to the new calendar. Figuring out where 2290 fits on the leap year schedule of our calendar to add in the extra day per 4 years.

The new calendar is a standard 220 23 hr days, as opposed to our 364/365 of 24hr days.
