A lunar month runs slightly shorter than a solar year, so roughly every 32-33 months an extra lunar month is inserted to keep festivals aligned with the right season. This is called Adhik Maas or Malmas. In 2026, that extra month falls as Jyeshtha, which is why Jyeshtha occurs twice this year.

How Adhik Maas is determined

If the Sun does not transit into a new sign (rashi) during a given lunar month, that month is treated as Adhik (extra). This rule is applied directly in our own month engine, not an approximation.

The exact 2026 dates

Computed from our month engine:

  • Adhik Jyeshtha: May 17 to June 15, 2026
  • Nija (regular) Jyeshtha: June 15 to July 15, 2026

What’s traditionally avoided during Adhik Maas

Tradition avoids auspicious activities like weddings, griha pravesh, and new beginnings during Adhik Maas. This year that window runs May 17 to June 15.

What Adhik Maas is actually for

Adhik Maas isn’t just a month to sit out. It’s also called Purushottam Maas, dedicated to Vishnu in his Purushottam form, and it carries its own set of practices rather than a blanket pause on life.

Families who observe it closely often do a daily reading of the Purushottam Maas Mahatmya, a set of chapters usually pulled from the Padma Purana or Skanda Purana, one chapter a day for the roughly 29-30 days of the month. Daan (charity) is treated as especially fruitful in this window: the classic form is 33 items of a kind, such as 33 types of fruit, or donations in units of 33, tied to the 33 categories of deities in Vedic cosmology. Til (sesame) and ghee daan are common too, since Adhik Maas overlaps with the hot pre-monsoon stretch in most years.

None of this is mandatory. Plenty of families treat the month like any other and only hold back on the wedding and griha pravesh side. If your family follows a specific sampradaya (tradition lineage), what’s observed can vary quite a bit, so this is worth a quick call to a grandparent or family priest rather than assuming one rule fits every household.

Planning around it if you live abroad

The practical problem for most NRI families isn’t the ritual calendar, it’s logistics. If you’re booking a venue in India for a wedding, engagement, or griha pravesh 8-10 months out (which is normal for anything in Delhi, Mumbai, or a Tier 1 city during peak season), you need to know Adhik Maas dates before you sign a contract, not after.

Two things trip people up every cycle:

  • Venue calendars don’t flag it. A banquet hall in Jaipur will happily take your deposit for a June 5, 2026 date without mentioning it falls inside Adhik Jyeshtha. The onus is on you to check.
  • Adhik Maas doesn’t repeat on a fixed schedule. It’s not every third year like a leap year. The gap is usually 32-33 months but can occasionally stretch closer to 34, since it depends on when the Sun’s sign transit and the lunar month actually line up. After 2026’s Adhik Jyeshtha, the next extra month falls in 2028, and its name changes depending on which lunar month gets doubled that cycle.

If you’re coordinating a date from the US, UK, or Australia and can’t easily ask someone on the ground in India, cross-check the date against the panchang page before you commit, rather than relying on a venue coordinator’s calendar or a WhatsApp forward from an aunt. It takes thirty seconds and it’s the one step that’s cheap to skip and expensive to get wrong.
