 | Calendars interpret time intervals in terms of years, months, days. Various calendars commonly in use in the
   scientific community are supported.
 
+Available calendars
+-------------------
+
+The following calendars are available in DART. The base date is used to define the origin of the 
+calendar system. For example, the Gregorian calendar has a base date of January 1, 1601, at 00:00:00. 
+This means that the all the DART time values in days,seconds in the Gregorian calendar are relative to this 
+starting date. If NO_CALENDAR is used, there is no concept of day, month, year: time is only days, seconds from 0.
