How the Tibetan calendar works

• The Tibetan calendar is lunisolar — each year has 12 (or, in leap years, 13) lunar months beginning and ending on a new moon, with months periodically added to stay aligned with the solar year — this is why Tibetan holidays drift against the Western calendar and fall on different dates each year.
• It is related to but not identical with the Chinese calendar — Tibetan astrology fuses indigenous Bon, Chinese-derived element/animal astrology and Indian Kalachakra star astrology — this is why Losar often falls near Chinese New Year yet can differ by a whole month.
• Lunar days (tithi) are not equal to solar days — a tithi is the time the moon takes to cover 1/30th of the new-moon-to-new-moon arc, so it can be shorter or longer than 24 hours — this mismatch between lunar and solar days is the root cause of doubled and skipped dates.
• Some calendar dates are DOUBLED and some are SKIPPED/OMITTED (called lhag, added, and chad, omitted, days) — you cannot simply count days off a Western calendar — a Tibetan month may lack a '30th' or repeat a number, which is why a published almanac is needed for exact dates.
• Certain lunar days are 'multiplying days' on which the karmic effect of actions is traditionally believed to be multiplied — the full moon (15th) and new moon (30th) monthly, and the four great Duchen festival days by the largest amounts — this is why practitioners concentrate virtuous activity, fasting and precept-taking on these days.
• The lunar day, combined with the weekday, the lunar mansion and one's birth animal-sign, is used to choose AUSPICIOUS TIMING for undertakings — travel, business openings, moving house, medical treatment, a child's first haircut — this electional use — picking a 'good day' — is the everyday practical function of the calendar for many Tibetans and Buryats.
• The year itself carries an animal + element pairing on a 60-year cycle, and 2026 is the rare Fire Horse year (royal year 2153), beginning at Losar on February 18, 2026 — this is why the whole year, not just individual days, is given an astrological character, and why a 60-year-recurrence year draws special attention.

Traditional/reference information; exact Gregorian dates of recurring observances vary by lineage and require a published almanac.
