Losar: Welcoming the New Year Across the Himalaya

Reference library · 966 words

Losar is a plain name for a complicated festival. Lo means year and sar means new, and the two syllables cover a new year observed from Lhasa to Ladakh, from Bhutan to the Tibetan settlements of southern Karnataka, on dates that frequently do not agree with one another. Two Himalayan towns a day's drive apart may hold Losar six weeks apart and both be entirely correct. Understanding why is the fastest route into what the festival actually is.

The Calendar Does the Complicating

The Tibetan calendar is lunisolar. It runs twelve lunar months, with a thirteenth added every two or three years so that the average year keeps pace with the sun. Years are named within a sixty year cycle called the rabjung, formed by pairing five elements, wood, fire, earth, iron and water, each in a male and a female aspect, with the twelve animals. A year is therefore not a number but a description, such as the female wood snake year.

The system has a further peculiarity that surprises visitors reading an almanac for the first time: certain dates are omitted and certain dates occur twice, because the lunar day and the natural day do not align neatly. On top of that, more than one calendrical tradition is in use. The Phukpa system, established in the fifteenth century, is the most widely followed; the Tsurphu tradition of the Karma Kagyu lineage dates from the thirteenth; and calculations descending from Kalachakra astronomy underlie both. Different monasteries and regions have historically followed different reckonings, and local determination of the date is normal rather than exceptional.

This is why Losar most often falls in February or March but does not reliably coincide with Chinese New Year, even though the two calendars share ancestry and sometimes land on the same day. In Ladakh, Losar is kept roughly two months earlier than the Tibetan date, in the eleventh month. The traditional explanation is that a Ladakhi ruler brought the festival forward so that it could be observed before an army departed on a winter campaign. It is a good story, and it is a tradition rather than a documented event. In Nepal the picture multiplies again: Sonam Lhosar is kept by Tamang communities weeks before the Tibetan date, Tamu Lhosar by Gurungs at the turn of the winter, and Gyalpo Lhosar aligns with the Tibetan reckoning. Losar names a family of new years, not one date.

Older Than Buddhism

The festival is generally understood to predate the arrival of Buddhism in Tibet. Its roots are traced to a winter incense burning custom associated with Bon, the indigenous Tibetan religious tradition, which merged with a harvest observance to become an annual event. Traditional accounts place this consolidation in the reign of an early Yarlung king. These regnal dates come from Tibetan historical tradition rather than from independent evidence, and should be treated as such.

Bon itself is less simple than popular writing suggests. Scholars disagree over how much of the organised Bon tradition preserves genuinely pre Buddhist material and how much was systematised later alongside Buddhism. What is reasonably clear is that early Tibetan ritual life included propitiation of local spirits and mountain deities, and that this layer survives inside Losar as smoke offerings and flag raising, sitting comfortably beside monastic Buddhist observance.

What Actually Happens

Preparation begins well before the day. Houses are cleaned exhaustively, and the sweepings and old goods are discarded in a deliberate clearing out of the year's accumulated misfortune. Kitchens produce khapse, fried wheat pastries in twisted and looped shapes, stacked into towers on the household altar. A chemar box is filled with roasted barley flour on one side and barley grain on the other, decorated and offered to visitors, who take a pinch and toss it upward in greeting. Barley is sprouted in advance so that green shoots stand on the altar in midwinter. Chhaang, the barley beer, is served warmed and enriched as changkol.

The eve of the final days brings guthuk, a thick noodle soup eaten on the twenty ninth of the last month. Large dumplings are dropped in containing hidden tokens: wool, charcoal, chilli, salt, a coin, a scrap of paper. Each token is a comic verdict on the character of whoever finds it, and the meal is a licensed evening of teasing. It is followed by a ritual expulsion of negativity, in which torches are carried out of the house and refuse is dumped at a crossroads or thrown away from the settlement.

The days that follow have distinct characters. The first is domestic, spent with immediate family and marked by an early rising and a formal exchange of greetings. The second widens to relatives, neighbours and, historically, to officials and monastic institutions. The third is the day for prayer flags: old ones are taken down and new ones strung across rooftops, bridges and ridgelines, with juniper burned as a purifying smoke offering. Monasteries hold masked cham dances in the surrounding days, performances that are religious ritual rather than entertainment, though they draw crowds of both kinds.

Where It Is Kept Now

Losar is observed across Tibet, in Ladakh, Spiti, Lahaul, Sikkim and the Monpa areas of Arunachal Pradesh, throughout Bhutan, in the Himalayan districts of Nepal, and in the Tibetan settlements established in India after 1959 at Dharamshala, Bylakuppe, Mundgod and elsewhere.

Exile changed its register. For Tibetan communities outside Tibet the festival became a marker of continuity and, inevitably, a political occasion, and in years following major loss of life or political crisis exile communities have chosen to keep Losar in a subdued form, with prayers and no celebration. That decision is renewed year by year and is itself argued over. For a festival built on clearing out the old and starting fresh, the tension is not accidental.
