The Three Bihus of Assam: A Complete Guide to Bohag, Kati, and Magh

One state, three Bihus, three completely different moods. Here's what actually happens during Bohag, Kati, and Magh Bihu, and why each one feels so different from the others.

Most places celebrate one big harvest festival a year. Assam has three, and they don't feel remotely alike. Bohag Bihu is loud and joyful, Kati Bihu is quiet and almost solemn, and Magh Bihu is a full-on feast. Together they trace the entire agricultural year, from sowing to the lean months to the final harvest, and understanding all three tells you more about Assamese life than any single festival could.

Bohag Bihu: The Assamese New Year

Bohag Bihu, also called Rongali Bihu, opens the Assamese calendar year and marks the start of the sowing season. In 2026 it runs a full week, from April 14 to April 20, with the main public holiday on April 15. This is the Bihu most people picture when they think of Assam: the Bihu dance performed in vibrant traditional dress, dhol drums, the pepa horn, and households cooking pitha, rice cakes made in dozens of regional variations. The first day, Goru Bihu, is set aside specifically for cattle, who are bathed and fed special offerings in gratitude for their role in farming. It's a genuinely joyful week, treated as the emotional start of the year regardless of what the Gregorian calendar says.

Kati Bihu: The Quiet Bihu

Kati Bihu, observed on October 18 in 2026, couldn't be more different in tone. It falls during Assam's leanest agricultural stretch, when the new paddy hasn't ripened yet and granaries from the last harvest are running low, which is why it's also called Kongali Bihu ('Kongali' meaning poor). There's no dancing here. Instead, families light earthen lamps, called saki, near the tulsi plant, in the granary, and out in the paddy fields themselves. A special lamp called Akash Banti is tied to tall bamboo poles in the fields; practically, it draws crop-damaging insects away with its flame, but the ritual reading is about seeking protection and patience until the harvest comes in.

Magh Bihu: The Feast After the Harvest

Magh Bihu, also known as Bhogali Bihu, is the reward for the year's work. Landing on January 15 in 2026 (with the eve, Uruka, on January 14), this is when the rice harvest is finally in and there's something to celebrate properly. The night before, communities build temporary huts called bhelaghar from bamboo and hay, cook a communal feast, and gather around it. The next morning, the bhelaghar is burned in a bonfire called Meji, and the ashes are scattered back over the fields, a small act of returning something to the land that just fed everyone. Traditional games, including buffalo fights in some districts, round out the day.

Why Three Bihus Matter

Seen together, the three Bihus aren't really three separate festivals so much as three chapters of the same story: sow with hope (Bohag), wait with patience (Kati), and celebrate with gratitude (Magh). That's a rhythm most people, even outside Assam, can recognise, which is probably why Bihu has become one of the most widely understood regional festivals in India, well beyond the state's own borders.
