How to use it
  1. Enter a Badí year (B.E.).
  2. Read each month's Feast date.
Formula
Each of the 19 months' first day is derived from that Badí year's Naw-Rúz date plus a fixed day-offset, accounting for the Ayyám-i-Há intercalary days inserted before the final month.
Worked example

In Badí year 183 (starting Naw-Rúz 2026): the 2nd month (Jalál) begins April 8, 2026.

Interpreting your result
