About the Theravada Holiday Calculator
Computes Magha Puja, Asalha Puja, and the Kathina robe-offering window for any Gregorian year — Theravada-specific observances derived from the Indian Panchang's lunisolar calendar.
- Enter a Gregorian year.
- Read Magha Puja, Asalha Puja, and the Kathina window dates.
In 2026, this calculation gives Magha Puja February 1 and Asalha Puja June 29 — check your own country's published date, since the real-world variation here can be substantial.
Like Vesak, these are computed from the Indian Panchang's lunisolar reckoning — one real convention, not a universal one. Southeast Asian countries' own civil Buddhist calendars can place these dates up to a month apart: confirmed directly while building this tool, Thailand's own published 2026 Magha Puja date is a full month after this calculation's.
- • The Kathina window is a full month long, not a single day — lay supporters can offer robes and requisites to the monastic community on any day within it, traditionally at a single ceremony chosen by each monastery.
