hijri-core / HijriYearRecord

Interface: HijriYearRecord

Defined in: types.ts:26

One row in the Umm al-Qura reference table.

The table covers Hijri years 1318-1500 (Gregorian 1900-2076). A sentinel row at hy=1501 with dpm=0 marks the upper boundary and is used to detect out-of-range inputs without a separate bounds check.

The dpm bitmask encodes month lengths for all 12 months: bit i (0-indexed from bit 0) = month i+1; 1 = 30 days, 0 = 29 days.
