Adhikamas(Malmas)-
According to the Vashishtha principle, the Indian calendar runs according to the calculation of the solar month and the lunar month. Adhikamas is an additional part of the lunar year, which comes every 32 months 16 days and 8 Hrs. It appears to balance the difference between the solar year and the lunar year. According to the Indian calculation method, each solar year is of 365 days and about 6 hours, while the lunar year is of 354 days. There is a difference of about 11 days between the two years, which equals to about 1 month every three years. To bridge this gap, a lunar month comes into existence every three years, which is named Adhikamas or Malmas because of its extra month.
