# Interface: HijriYearRecord

Defined in: [types.ts:26](https://github.com/acamarata/hijri-core/blob/94bc28ebc35ae2f3cb39db5be34561152a5b899d/src/types.ts#L26)

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.
