Adhik maas

Note - on eclipse days, recite Vishnu Sahasranamam - go back and add all the Dwadashi days, and the notes of the names of the Ekadashis.
Year begins with Chaitra, which contains the first Shukla pratipad in Meena sun sign
If there are two lunar months starting (under the Amavasya system) -- or two shukla pratipads - in one solar month, the first becomes adhik maas.
