Mal Maas: Meaning, Rules and the Next Date

Every few years, the Hindu calendar adds one extra month, and the name often confuses people. Many wonder if it is good or bad, and what they should do during it. This month is known as mal maas, and it is also called adhik maas. The last one ran from 17 May to 15 June 2026. Read on to understand its meaning, the rules people follow, and the date of the next one.

Meaning and Calendar Logic

People often ask what is adhik maas and why the calendar needs it. The reason is a simple gap between two ways of counting time. The Hindu calendar follows the Moon. A lunar year has about 354 days, while a solar year has about 365 days. That leaves a gap of nearly 11 days every year. Left alone, this gap would push festivals into the wrong seasons over time. So one extra month is added roughly every 32 to 33 months, on average.

This is what adhik maas means in practice: a month that brings the lunar and solar counts back in line.How does the calendar choose which month to repeat? Each lunar month normally has one Sankranti, the day the Sun moves from one zodiac sign to the next. A lunar month with no Sankranti is treated as the adhik month.

Why It Is Called “Mal” and How It Became Purushottam

The word “mal” means impurity. Every other lunar month has a ruling deity, but this extra month had none. In simple terms, it was a month without an owner. Because of that, it was seen as unfit for auspicious work, and people began calling it mal maas.

The Padma Purana tells what happened next. The neglected month approached Lord Vishnu and shared its trouble. Vishnu accepted it as his own and named it Purushottam, which means the supreme being. That is how it became known as purushottam maas. So the name “mal” does not mean the month is bad. It only shows that weddings, housewarmings and similar events are paused. The month itself is kept for prayer, charity and quiet worship.

What to Do and What to Avoid

Most families follow a few simple rules during mal maas. The month is meant for worship and giving, so anything that starts something new is usually put off until the next regular month.

What to do

• Chant the Vishnu Sahasranama or the mantra “Om Namo Bhagavate Vasudevaya” every day.
• Read or listen to the Bhagavata Purana.
• Give daan in the form of food, clothes or grain, and light lamps as deep-daan.
• Observe the Padmini Ekadashi and Parama Ekadashi fasts, which fall in this month.

What to avoid

• Marriage ceremonies.
• Griha pravesh, the housewarming ceremony.
• Mundan, the first haircut, and Upanayana, the sacred thread ceremony.
• Buying a new vehicle.
• Starting a new vrat.

These are traditional practices, and customs differ between families and regions. For an urgent ceremony, a family pandit can advise on the right date. Daily puja and regular worship continue as usual.

Common Beliefs People Ask About

Is a Birth in This Month Unlucky?

Some people believe a child born in adhik maas needs a special ritual. Others see the birth as a blessing in a month of devotion.
Traditions differ, and no single rule fits every family. There is no firm claim that such a birth brings harm. For ceremonies such as naming, a family pandit can suggest the right date.

Next Adhik Maas After 2026

The next Adhik Maas 2029 is Adhik Chaitra, from 16 March to 13 April 2029. It comes 34 months after the 2026 one began in May. If you plan a wedding or griha pravesh in spring 2029, keep this window in mind. Many families avoid these ceremonies during the adhik month, so it is better to check the dates early. Confirm the exact dates with a local panchang.
