The Markelsian calendar is a 13-month calendar proposed in 2000 by Minot State University psychology professor Dr. Paul Markel, based on the thirteen Zodiac constellations.
The calendar has twelve 28-day months, and a thirteenth month of 29 days called Ophiucus. The first and twenty-eighth days of each month are always Sunday and Saturday, respectively. Every leap year an additional day, called Julius, is observed immediately after 29 Ophiucus; this day does not belong to any month, but is referred to as the Corrigendum.

|02||Capricornus||28||Jan 15 - Feb 11|
In the Markelsian Calendar, the last day of the year is Sunday, Ophiucus 29 (December 17) and the first day of the year is Sunday, Sagittarius 1 (December 18).
Markel says of this feature of his calendar:
- "This presents a unique feature of the Markelsian Calendar, the "Long Sunday", which is a celebration of New Years over a 48-hour "period of rest" or Sabbath (the last and first days of the year comprise a 48-hour Sunday in the Markelsian Calendar). Long Sunday thus challenges the notion of Sabbath and is an example of a cultural paradigm shift that will likely arise with any proposal of calendar reform."
