Assam has three Bihus and only one of them is a celebration

One name, three moments in the agricultural year

Visitors to Assam frequently hear about Bihu and assume it is a single spring festival. It is three separate observances spread across the year, all called Bihu, each tied to a specific stage of the rice cycle that has organised life in the Brahmaputra valley for a very long time.

Rongali or Bohag Bihu falls in the middle of April at the start of the agricultural year and is the great celebration. Kati or Kongali Bihu comes in the autumn, when the crop is in the field and the granary is at its emptiest. Magh or Bhogali Bihu arrives in the middle of January after the harvest is in.

Read in that order the logic is obvious. The three festivals mark hope, anxiety and satisfaction respectively, and the mood of each follows directly from what is happening in the fields at the time. It is one of the clearest surviving examples of a festival calendar that is really an agricultural calendar.

Rongali Bihu is the one everyone means

The April festival is the Assamese new year and the largest public celebration in the state. It runs over several days, each with its own character, beginning with observances involving cattle, who are washed, decorated and honoured for the year’s work ahead.

The public face of it is the dance and the music. Bihu dance is performed in groups, with a distinctive rhythm carried by the dhol drum, the pepa horn made from buffalo horn and other traditional instruments, and it happens both in organised performances and informally wherever people gather.

Because it falls at the same solar moment as several other regional new year festivals across India, the middle of April is a busy travel period across a wide swathe of the country. In Assam specifically, expect the state to essentially stop for several days, with offices closed and a great deal of movement as people return to home villages.

Kati Bihu is the austere one and it is easy to miss

The autumn Bihu is entirely different. The name Kongali carries the sense of poverty or scarcity, because it falls at the point in the year when the previous harvest has largely been consumed and the standing crop is not yet ready. There is no feasting and no dancing.

What happens instead is quiet and domestic. Earthen lamps are lit in the courtyard, at the base of the sacred tulsi plant and in the paddy fields themselves, and prayers are offered for the crop’s protection. In the fields the lamps have a practical rationale as well, in drawing insects away from the plants.

For a traveller this is the least visible of the three and the most atmospheric if you happen to be in a village for it. There is nothing to attend in the sense of an event. There is a landscape of small lights after dark, and that is the whole of it.

Magh Bihu is the harvest festival and it is a communal one

The January Bihu comes after the harvest and shares its moment with the solar harvest festivals celebrated across much of India in the same week. In Assam the distinctive feature is the temporary structure — a large hut built of bamboo, thatch and leaves, raised in a field for the occasion.

The community gathers there through the night, and the structure is burnt in the morning as part of the observance. Traditional games associated with the festival, including forms of buffalo and bird contests in some places, have been the subject of legal restriction and considerable public argument, and the position has changed more than once.

It is a village-centred festival more than a public spectacle, and a visitor is much more likely to see it properly through a homestay or an invitation than by turning up in a town expecting a programme.

Planning around the Bihu calendar

The two big Bihus, in April and January, are travel-heavy weeks in Assam and across the northeast more broadly. Transport within the region fills, some businesses close for several days, and the connections into the region from the rest of the country are under pressure at the same time.

They are also the best weeks of the year to be there if the object is to see the culture rather than the landscape. April in particular puts the whole state in a festival mood, and the weather at that point — warm, before the heavy rains establish themselves — is more comfortable than what follows.

Exact dates shift slightly and the programme of public events is organised locally each year, so the current position is worth checking with a local source rather than relying on a general calendar. What does not change is the sequence, and understanding that sequence explains more about rural Assam than any amount of sightseeing does.
