ADHIK MAAS/ADDITIONAL OR EXTRA MONTH/ PURSHOTTAM MAASWhat is Adhik Maas
The Hindus follow two types of calendars - The solar calendar and lunar calendar. The solar year is made up of approximately 365 days whereas the lunar year is made up of approximately 354 days. Thus there is a gap of about 11 days between these two types years. This gap increases each year and in about three years it equals to one month approximately. To cover this gap, one additional month is added to the lunar year in approximately two and a half years. Thus Adhik maas or extra month balances the lunar and the solar calendar.
Adhik maas has one name i. e. Aashadh or Shravan or Bhadrapad etc. but it has about 60 days or two months. These two months are known as the first month and the second month.
In the Vikram Samwat 2069, the month of Bhadrapad was the additional month or Adhik maas. So Bhadrapad was known as first Bhadrapad and the second Bhadrapad.
Thus in the light of the above illustration, it can be concluded that whatever the Vrat or festivals are celebrated, will be celebrated in the pure month or Suddha maas. In the above illustration the Shuddha maas is from 3.8.2012 to 17.8.2012 and from 1.9.2012 to 16.9.2012.
