2027 Tibetan Buddhist Calendar — Female Fire Sheep Year (2154) & Leap Month 2

Under the canonical 1447 CE Men-Tsee-Khang Phugpa calculation, Tibetan Royal Year 2154 (17th Rabjung Female Fire Sheep, me-mo-lug-lo) begins with Losar on February 7, 2027. Chötrul Düchen falls on February 20, 2027 (14 days after Losar because the 14th lunar tithi is astronomically omitted after February 19). Because 2027 contains an intercalary Leap 2nd Month, Saga Dawa Düchen (4th Month, 15th Day) falls on June 18, 2027, Chökhor Düchen on August 6, 2027, and Lhabab Düchen on November 20, 2027.

A lunar year of 12 synodic months (~354.37 days) is ~10.88 days shorter than a solar tropical year, so Kālacakra Phugpa astronomy inserts an intercalary leap month (zla-bshol) roughly every 32.5 lunar months whenever a true lunar month contains no solar zodiacal ingress (saṅkrānti). Under the classical Men-Tsee-Khang Phugpa convention, the intercalary month carries the number of the upcoming regular month and precedes it—so 2027 runs Month 1 → Leap Month 2 (March 8 – April 6, 2027) → Regular Month 2 (April 7 – May 6, 2027). Major annual commemorations belong to the regular month.

Because in Month 1 of Tibetan Year 2154, the 14th lunar tithi completes its 1/30th arc between the sunrises of February 19 and February 20, making Lunar Day 14 an omitted tithi (chad, ཆད). February 19 is Lunar Day 13, and sunrise on February 20 is already Lunar Day 15 (Full Moon Chötrul Düchen). Always check an authentic Phugpa almanac rather than adding 14 calendar days by hand.

In Tibetan sacred geography, each major holy mountain and turquoise lake has a twelve-year zodiacal birth-year kora: Horse Year (2026) is the great year of Mount Kailash (Gang Rinpoche), whereas Sheep Year (2027, lug-lo) is the twelve-year pilgrimage year of Lake Namtso (གནམ་མཚོ།, “Heavenly Lake” north of Lhasa, sacred to Cakrasaṃvara and Vajravārāhī), when pilgrims circumambulate its high-altitude shoreline.
