Adhik maas

 In the Hindu calendar, Adhik Maas (also spelled Adhik Mas or Purushottam Maas) is called the “intercalary month” or “leap month” in English.

Adhik Maas is an extra month added roughly every 32.5 months to align the lunar calendar with the solar year. Without it, lunar months would drift away from seasons and festivals.

It is also commonly known as:

• Purushottam Maas — a devotional name, especially in Vaishnav traditions, associated with Vishnu / Purushottam.
• Malamas — a traditional term used in some regions.

For example, if an extra lunar month falls in the period of Shravan, it may be called “Adhik Shravan.”
