Wan Phra Calendar

Wan Phra Calendar shows every Thai Buddhist observance day — wan phra (วันพระ) and the great Bucha days — computed from the Thai lunisolar calendar and validated against officially published dates.

WHAT YOU GET • Every wan phra: the full moon, the new moon, and the two half-moon days (ขึ้น/แรม ๘ ค่ำ) • The five great days: Makha Bucha, Visakha Bucha, Asalha Bucha, Khao Phansa, and Ok Phansa — with the correct month shifts in athikamat years • Reminders that arrive on wan kon (วันโกน), the evening before — or up to a week ahead, at the time you choose • Thai and English, switchable in the app; Buddhist Era (พ.ศ.) alongside the common era • Add your own dates — memorials, retreats, anniversaries — with their own reminders • Add your own artwork to any observance day

ACCURATE BY DESIGN Dates are computed with the traditional Thai lunisolar rules, including athikamat (extra-month) and athikawan (extra-day) years, and validated against official Thai Bucha dates across many years.

PRIVATE BY DESIGN No accounts, no tracking, no servers. Everything stays on your phone.
