Kathina - the robe offering that closes the rains retreat in Theravada Buddhism
Kathina is the Theravada robe-offering festival that marks the end of the Vassa rains retreat, falling in the lunar month after Vassa. Each monastery chooses its own day within that month, so unlike most Buddhist holidays it has no single fixed date.

Kathina is the Theravada robe-offering festival that closes the rains retreat. Where most Buddhist holidays fall on a fixed date in the lunar calendar, Kathina occupies a whole month - and each monastery picks its own day inside it, so there is no single date for the festival.
The one-line summary
Theravada robe offering closing the Vassa rains retreat, celebrated in the lunar month after Vassa with no fixed date. Religious category, standard tier, and observed across Thailand, Laos, Cambodia and Myanmar. Not a statutory public holiday anywhere, but widely kept.
Origin
The festival takes its name from the Pali kaαΉhina, literally loose cloth or the outer robe, and the whole of its meaning is in that one word. Under the ordinary Vinaya rules a robe can only be offered to a single monk at a time, and it cannot be offered at all during the rains retreat while the community is stationary.
The account that grounds the exception runs as follows. During the retreat one monk fell ill, and the physician advised that he would recover sooner if he could be given a new robe. Since no monk could leave to beg, he was given an old discarded cloth to wrap himself in instead. The sight of a senior monk covered in a rag rather than a proper robe moved the other monks, and the Buddha ruled that for the remainder of the rains and the month following, the laity might offer robes directly to the sangha as a body. That exception is what Kathina celebrates.
When it falls
Because Kathina is defined by a window rather than a date, the year-to-year pattern is unusual. The season opens in the lunar month following the end of Vassa, which puts it in about October or November in the Gregorian calendar. The opening of that window falls roughly two days after the full moon of the eleventh lunar month - so the season opens on 27 October 2026, 16 October 2027 and 4 October 2028.
Individual observances then scatter across the rest of the month. Monks will often hold the ceremony on a weekend, and will sometimes repeat it on several weekends so that lay donors working through the week can take part in one. In Myanmar in particular the festival has developed an extended family celebration around the donation, with dedicated foods and a social component well beyond the robe itself.
How it is observed
The central act is the assembly and offering of the robes. Donors bring cloth or complete garments; these are cut up and sewn together into single outer robes, often by the nuns of the community - and that patchwork is the point. The robe is a material record of who contributed, which is why the making of it is as significant as the gift.
The finished robes are then stacked, often on a tiered frame, and candles are set around them; the robes are formally offered to the sangha and the candle-lit structure is carried in procession before being taken apart and distributed. The associated mood is one of rejoicing - the festival is commonly described in the sources as the pavΔravΔda, the declaration of joy - and it is the one major Buddhist festival where the laity, rather than the monastics, are the protagonists.
Public status
Kathina is not a statutory public holiday in Thailand, Laos, Cambodia or Myanmar, in contrast to the closely related Asarnha Bucha a month earlier. It is, however, widely observed, and monasteries, temple schools and religious organisations very commonly close for it. The absence of legal status is one of the things that distinguishes it from its neighbours on the Theravada calendar, and it is a good illustration of why a festival calendar cannot assume that a widely kept observance is a statutory day off.
Related holidays
Kathina sits betweenAsarnha Bucha - which ends Vassa a month or so earlier - and the water and lantern festivals that close the lunar year.Loy Krathong and the Khmer water festival both fall on the full moon of the twelfth lunar month, about a month after Kathina has finished.
