The Martiana Calendar at a Glance

Notes:

1. This is a variant of the Darian calendar. Differences are:

   • The relationship between the days of the week and the months repeats over a biennial cycle. Even-numbered years begin on the first sol of the week. The months within each quarter begin on the first day of the week.

   • Uses the epoch 11 Mar 1609 instead of 17 Dec 1975.

2. This is one of several Symmetric Vernal Equinox Martian calendars, which generally have the following characteristics:

   • Divide the Martian year into 24 months of approximately equal duration.

   • Retain the seven-day week.

   • Begin the year on the vernal equinox

   • Place the leap day(s) at the end of the year.

3. Other types of 24-month calendars are:

   • Symmetric Double Gregorian Martian calendars

   • Asymmetric Vernal Equinox Martian calendars

   • Symmetric Summer Solstice Martian calendars
