Chaturmas Food Rules: Four Phases, Not Four Months

Chaturmas asks you to give up one food at a time, not all four at once.

The four months are cut into four windows, and each window forbids a single thing: leafy greens, then curd, then milk, then pulses. Today the live rule is the fourth one. Pulses.

That sequence is the part that goes missing. Most of what is written about Chaturmas food in English collapses it into a single list — give up greens, give up curd at night, eat once a day — three instructions with no dates attached and no indication that they take turns.

Key takeaways

• Chaturmas 2026 runs from Devshayani Ekadashi, Saturday 25 July, to Friday 20 November.
• It divides into four windows of about a lunar month each: greens, then curd, then milk, then pulses.
• The fourth — dvidala vrata, the pulse rule — began Friday 23 October 2026.
• Each window runs Shukla Dwadashi to the next month's Shukla Ekadashi, so none of the four matches a named month.

Which rule is in force right now?

The fourth one. Pulses are the food set aside, and have been since Friday 23 October.

The day-panchang is unusually plain about this. It carries a row for it, and the row counts: on 25 October 2026 it reads 4th Chaturmasa Day 3, with a small bean beside it. On 23 October it read 4th Chaturmasa Begins. On 22 October, the day before, it read 3rd Chaturmasa Last Day — the milk window closing.

So the question has a different correct answer depending on the week you ask it. The whole sequence for 2026:

Why does no food match a named month?

Because the windows are not months. They are Ekadashi to Ekadashi, and that is a different thing.

You will read that curd is given up in Bhadrapada and milk in Ashwin. Set that against the dates: the curd window ran 24 August to 22 September 2026. It opens in one lunar month and closes in the next, and it does that whichever reckoning your family uses, because a named lunar month is bounded by a new moon or a full moon and these windows are bounded by neither.

What bounds them is the Ekadashi chain. Each window opens on the Shukla Dwadashi — the morning after an Ekadashi, which is the parana day, when the previous fast is broken — and closes on the next month's Shukla Ekadashi. Then the next window opens the following morning. Every Ekadashi in the chain does double duty: it is the last day of one window and the hinge into the next.

Five Ekadashis, four windows. Drik Panchang states the frame as Ashadha Shukla Ekadashi to Kartika Shukla Ekadashi and notes that it begins each count from the Dwadashi tithi, which is exactly the offset you can see in the table.

An Ekadashi-bounded window is about a lunar month long and sits eleven days out of step with any month that has a name. So a one-food-per-month listing is not slightly imprecise. It is wrong by construction, and it will be wrong every year. If you want to know which rule is live, the only reliable move is the same one that settles the parana window on an ordinary Ekadashi — read the day's own panchang row rather than a rule of thumb.

What does dvidala actually mean?

Two-lobed. That is the whole word: dvi, two, and dala, a split or a leaf.

It is a description of a shape rather than of a plant family. Press a soaked chana between your fingers and it comes apart into two identical halves — that clean symmetrical split is what the word is pointing at. Moong, masoor, urad, chana, moth: all of them do it, which is why a single term covers the lot without listing them. The panchang glosses it as grains divided into two identical parts, known in plain language as pulses.

It is worth noticing how precise that is next to the other three names. Shaka is greens, dadhi is curd, dugdha is milk — three ordinary nouns for three ordinary things. The fourth rule does not name a food at all. It names a structure and lets the kitchen work out what qualifies.

Why these four foods, in this order?

The reasons the tradition gives are seasonal, and they track the monsoon arriving and then withdrawing.

The panchang's own notes put it plainly enough. Greens come first because at the start of the rains the soil fills with insects and leaf vegetables are hardest to clean. Curd follows because curd turns quickly in that weather. Milk after that, on the reasoning that milk is altered during the rains. The order is not arbitrary; it is a calendar of what is most difficult to keep at each stage of a wet season.

The fourth is the one that does not fit the pattern, and that is what makes it interesting. By late October the rains have gone. Nothing about a dry Kartik morning makes a lentil harder to store. The pulse rule is reasoned differently in the texts — as a matter of digestion rather than spoilage — and it is the only one of the four named for the shape of the food instead of the food itself. Three housekeeping rules and then something else.

I would not push that observation further than it goes. These are prescriptions a tradition makes, not advice, and the household keeping them is usually not doing the reasoning at all — it is doing what the panchang says this month, the way it did last year.

When does the fourth window end?

Friday 20 November 2026. The panchang marks that day both 4th Chaturmasa Day 29 and Chaturmasa Last Day.

The close is the least tidy date in the whole sequence, and it is worth knowing why before you plan around it. The first three windows end on a Shukla Ekadashi at sunrise. This one does not: at sunrise on 20 November the tithi is still Shukla Dashami, and the Devutthana Ekadashi tithi only opens at 7:15 that morning. That is the source of the split you will see in family almanacs, where some households keep the day on the Friday and others keep Gauna Devutthana Ekadashi on Saturday 21 November. Our own piece on what the four months actually ask of you works through that end date and the weddings-and-muhurat side of Chaturmas in more detail.

The five days that follow — Bhishma Panchak, also called Vishnu Panchak — carry their own observance, which is a separate thing from the four food windows and not a fifth phase of them.

What is eaten instead?

Rice, wheat, the vegetables that are not leaves, fruit, root vegetables, ghee. In a pulse window that usually means the dal simply comes off the thali and something else takes the protein's place — paneer in houses that take milk, or sabudana, or singhare and kuttu flour, the same substitutions a Navratri kitchen already knows.

The practical difficulty of dvidala vrata is not hunger. It is that pulses are hidden in everything. Besan is chana. So is the batter on a pakora, the dhokla, the papad, the chutney thickened with roasted chana dal, the hing that has been cut with wheat or gram flour. A household keeping this window properly spends it reading labels and asking what the bhajiya was dipped in, which is a different and more tedious discipline than giving up curd.

That is the part of the observance nobody writes down, and it is the part anyone who has kept it will recognise. The rule is one line. Keeping it is a month of small questions in your own kitchen, and the panchang row that tells you which month it is will be waiting on the morning after the next Ekadashi, counting again from one.
