The Martian Common Era Calendar

An introduction		This informal introduction is good for the beginner. Most of us are unaccustomed to thinking in terms of how calendars work in general.
(Technical details - TBD)		More technical information will come later, including design considerations and the constants and algorithms used for calculations.
Current date/time		Refresh this page (or the iframe) to get the current date/time (for Earth and Mars).
Convert to MCE		Convert an "Earthly" date (Gregorian) to a Martian Common Era date.
API description		This site hosts an API for handling Martian date/times and interconversion. The documentation is accessible through /api with no parameters.
MarsDate Ruby gem		The API is written in Ruby, facilitated by the MarsDate gem which defines MarsDateTime.
Martian Birthday		A fun little project based on this calendar system. When is your Martian Birthday?
