Most Santali festivals aren't fixed Gregorian dates — they're tied to a specific moon phase (like Kunami/Full Moon or Mulug Etohob/First Crescent) of a specific lunar month. The site's engine locates that reference moon phase using Meeus' astronomical algorithms and resolves it to a Gregorian date fresh for every year you select.
Ol Chiki (ᱚᱞ ᱪᱤᱠᱤ) is the official writing system for the Santali language, created by Pandit Raghunath Murmu in 1925. It has its own unique alphabet and digits, and this site displays all months, days and festival names in both Ol Chiki and English.
Yes. Santali Calendar is an installable Progressive Web App — once installed, a service worker caches the pages, styles and scripts so the calendar, festivals and moon phases all keep working without an internet connection.
