Geodate

Geodate displays the current local time in a geocentric date format using a natural lunisolar calendar with metric time based on fractions of the mean solar day.

Be prepared to forget all about hours and minutes and start using centidays instead! For example noon is the middle of the day or 50 centidays after midnight.

You will also learn to be more in touch with the natural environment with this lunisolar calendar. For example the full moon will always be around the middle of every month, easy, just look up in the sky to know the time.
