- The idea was to create the most humanly readable modification of the
-<a href="https://en.wikipedia.org/wiki/Darian_calendar#Calendar_layout">Darian calendar</a>
- On contrary to the original, the epoch starts on UTC 00:00 11th April,
- 1609 (invention / first use of telescope) with year 1, not year 0. Aditionaly, the time zone with zero offset was chosen not
- conventionally (the first landing spot / prime meridian) but rather by matching the
- converted time with actual daylight on the Red Planet.
+ The idea was to create the most humanly readable modification of the Darian calendar.
+ I named it Scarlett calendar. Sol (a Martian day) has
+ 24 hours like Earth day, but Martian second is just slightly longer (as can
+ be seen in the clock itself) which results in day length of 24 hours, 37 minutes and
+ approximately 23 seconds. Martian weeks have 7 sols, every month has exactly 4 weeks and Martian
+ year has 24 months. This is basicaly same as in original Darian calendar. Complete
+ layout can bee seen
+ <a href="https://en.wikipedia.org/wiki/Darian_calendar#Calendar_layout">here</a>.
+</p>
+<p>
+ Differences start with the prime meridian, which was chosen not conventionally (the first landing spot of man-made object)
+ but rather by matching the time with actual daylight (sollight?) on the Red Planet.
+ This way, prime meridian happens to match the location of the highest mountain on Mars (and Solar System), Olympus Mons.
+ Because the difference, time zone with new prime meridian is called "0 offset time zone"
+ just to avoid confusion with the NASAs one (Airy-0).
+ Table below lists all time zones, with most notable landmark in it.

- Note, that original Darian calendar designates the first

day of each month as the start of a new week, which results in a one-day weekend occurring
- three or four times a year. I am uncertain how this would be received by future Martian
- colonists, so I didn't implemented this feature as well as
- winter/summer time shifts or any holidays whatsoever.

colonization candidates have a problem adopting a customized timekeeping
format due to their vastly different synodic rotation periods compared to
that of Earth. Homo sapiens are biologically programmed to function on a
- 24–26-hour day. Therefore, it is much easier to implement the classic
+ 24 to 26-hour day. Therefore, it is much easier to implement the classic
Gregorian calendar with a 24-hour day and disregard the actual daylight
period (especially since the thin atmospheres and natural luminous intensity
would require artificial lighting anyway).
