What is Adhik Maas?

Adhik Maas is the sacred extra month in the Hindu lunar calendar, added approximately every three years to synchronize the lunar and solar calendars. Also known as Purushottam Maas (named after Bhagwan Vishnu) and Mal Maas, it is considered the most auspicious month — dedicated to daily reading (Paath), chanting (Japa), charity (Daan), and fasting (Vrat). In 2026, Adhik Maas falls from May 17 to June 15 (Adhik Jyeshtha).

There is a month in the Hindu calendar that does not belong to any season. It does not mark a harvest or a festival. It arrives quietly, roughly once every three years, and for those who understand its significance, it is the most precious month of all.

This month is called Adhik Maas — the "additional month." It is also known as Mal Maas, and in our tradition, it carries a far more beautiful name: Purushottam Maas, the month of Lord Purushottam.

If you have heard your grandmother speak of this month with a particular reverence — if she set aside her usual routine, read a katha each day, gave to charity, and kept her mornings for Japa — this is the month she was observing. And there is a reason she treated it differently from all others.

Why Does the Hindu Calendar Have an Extra Month?

The Hindu lunar calendar is approximately 11 days shorter than the solar year. To prevent festivals from drifting across seasons, an extra month — Adhik Maas — is added roughly once every three years, based on precise astronomical calculations maintained by scholars for millennia.

The Hindu calendar follows the moon. Each month begins and ends with a new moon (in the Amanta system) or a full moon (in the Purnimanta system). A lunar month is approximately 29.5 days, which makes a lunar year roughly 354 days — about 11 days shorter than the 365-day solar year.

If nothing were done about this difference, the calendar would slowly drift. Festivals tied to particular seasons would wander across the year. Makar Sankranti, which marks the sun's northward journey, would eventually fall in monsoon. Holi, which celebrates the arrival of spring, would arrive in winter.

To prevent this drift, the Hindu calendar adds an extra month — Adhik Maas — roughly once every three years. This is not an arbitrary correction. It is a precise astronomical adjustment, governed by the movements of the sun and the moon, calculated by scholars for millennia. The extra month keeps the lunar calendar aligned with the solar seasons, so that festivals remain where they belong.

In this sense, Adhik Maas is the month that holds the calendar together. Without it, the rhythm of Hindu life would slowly come undone.

The Story of How Adhik Maas Became Purushottam Maas

According to the Padma Purana, the extra month had no presiding deity and was considered inauspicious — until Bhagwan Vishnu claimed it as His own, giving it the name Purushottam Maas and declaring that any devotion during this month carries more merit than in any other month. This story is the origin of the Purushottam Maas Mahatmya (Vrat Katha), traditionally read as one chapter per day during the 30 days of Adhik Maas.

Each of the twelve regular months in the Hindu calendar has a presiding deity — one of the twelve Adityas. But this thirteenth month, being "extra," had no deity of its own. It was considered inauspicious. No marriages were performed during it. No new ventures were begun. No sacred ceremonies were conducted.

The month was, in a sense, an orphan.

According to the tradition recorded in the Padma Purana, the personified Adhik Maas — grieved by this rejection — went to Vaikuntha and sought refuge with Bhagwan Vishnu. The month said: "I am unwanted among the other months. No one performs any auspicious work during my time. I have no presiding deity. I have no purpose."

Bhagwan Vishnu, who is called Purushottam — the Supreme Person, the one who transcends all others — looked upon this rejected month with compassion. He did something extraordinary. He gave the month his own name. He declared: "From this day, you shall be known as Purushottam Maas. Any devotion, any act of Dharma, any Daan, any Vrat, any Japa performed during your days will carry more Punya than the same act performed in any other month."

In one act of grace, the most neglected month became the most sacred.

This is why Adhik Maas is not treated as an unfortunate interruption in the calendar. It is understood as a gift — a month set apart from worldly concerns, dedicated entirely to spiritual practice. The very activities that are paused during this month (marriages, business ventures, house-warming ceremonies) are paused precisely so that there is room for what matters most: reading, reflection, Bhakti, and the deepening of one's relationship with Bhagwan.

When is Adhik Maas in 2026?

In 2026, Adhik Maas falls from May 17 to June 15. This is a period of Adhik Jyeshtha — meaning the extra month occurs alongside the regular month of Jyeshtha. It is sometimes called a "double Jyeshtha" year.

This is the first Adhik Maas since 2023 and presents 30 days of dedicated spiritual practice for those who wish to observe it.

How Often Does Adhik Maas Occur?

Adhik Maas occurs roughly once every 32 to 33 months — approximately once every three years. The exact timing depends on the astronomical relationship between the lunar and solar calendars.

Here are recent and upcoming Adhik Maas periods:

• 2023: Adhik Shravan (July-August 2023)
• 2026: Adhik Jyeshtha (May 17 - June 15, 2026)
• ~2029: The next Adhik Maas after 2026 (exact dates to be calculated)

The gap varies slightly each cycle. Sometimes the interval is closer to two and a half years; sometimes it stretches to three. But the pattern is consistent enough that families who observe Adhik Maas can plan ahead.

The Significance of Adhik Maas

Purushottam Maas is considered the most sacred month because it is Bhagwan Vishnu's own month — dedicated to accumulating spiritual merit through reading, Japa, Daan, and Vrat. The pausing of worldly activities creates space for families to read together, reflect, and deepen their relationship with Bhagwan.

Purushottam Maas holds a special place that no other month occupies. While every month has spiritual value, this month is considered uniquely powerful for several reasons.

It is Bhagwan's own month. The other months belong to the Adityas. This month belongs to Purushottam himself. Any practice performed during this time is understood to reach Bhagwan directly.

It is a month of accumulating Punya. The tradition teaches that reading sacred texts, performing Japa, giving Daan, and observing Vrat during Adhik Maas generates more spiritual merit than the same practices performed at any other time. This is not because the practices themselves are different, but because the month itself has been sanctified by Bhagwan's name.

It is a month of simplicity. Because worldly activities like marriages, new business ventures, and Griha Pravesh (house-warming) are traditionally avoided during Adhik Maas, the month naturally creates space. There is less social obligation, fewer events, fewer distractions. The tradition understood, centuries before anyone coined the phrase, that spiritual depth requires a clearing of the calendar.

It is a month for families. The daily reading of the Purushottam Maas Mahatmya — one chapter each day for the duration of the month — is traditionally done together. A grandmother reads aloud. The family gathers. The story is discussed. In this way, Adhik Maas is not a solitary practice but a shared one, a thread that connects generations.

What Makes This Month Different from Other Months

If you are encountering Adhik Maas for the first time, you might wonder: what actually changes during this month? How is it different from, say, Shravan or Kartik, which are also considered sacred?

The difference is in the intention. Shravan and Kartik have their festivals, their specific rituals, their association with particular deities and events. Adhik Maas has none of that. It has no festival. It has no mythological event tied to a particular date. It is, by design, empty — cleared of everything except the essentials.

This emptiness is the point. Adhik Maas is the tradition's way of saying: here is a month with no agenda. No wedding to attend. No business to launch. No ceremony to perform. What will you do with it?

The traditional answer is: read. Reflect. Chant. Give. Sit with Bhagwan and with the people you love. For 30 days, let the world's noise grow a little quieter, and see what you hear in the silence.
