What it means
Where is that year?
Years only: calendars start their years on different days, so near a new year the answer can be one off. A typed year is read as its first day.
The math
How to convert CE to HE
Most calendars add an offset: BE = CE + 543, AM ≈ CE + 3760, SH ≈ CE − 621. The Hijri year is AH ≈ (CE − 621.56) × 1.0307.
Example: 2000 CE = 12000 HE.
