The Tibetan calendar (ལོ་ཐོ།) is a lunisolar system rooted in the Kālacakra Tantra. Festival dates change each year because they follow the lunar cycle. Below are the major Düchen and festival days for 2026 according to the Phugpa tradition.
On the four major Düchen days, the karmic effects of positive and negative actions are said to be multiplied many times over.
Beyond the four great Düchen, every Tibetan lunar month contains three traditional practice days: the 10th (Guru Rinpoche / Tsok day), the 15th (full moon, Buddha Amitabha), and the 25th (Dakini day). On these days, practitioners traditionally offer prayers, light butter lamps, and observe vegetarianism.
Festival dates follow the Phugpa tradition. Tibetan dates and minor practice days are approximate (±1 day) due to skipped/doubled days that can only be calculated with the formal Phugpa astronomical algorithm.
For ritual purposes, verify exact dates with the official almanac at Men-Tsee-Khang.
