Convert between Gregorian and Hijri dates with optional moon‑sighting offset.
The Hijri calendar is based on moon sighting, which can vary by location. Some countries use astronomical calculations, while others rely on local sighting.
The offset allows you to adjust the Hijri date by ±1 or ±2 days to match your local moon‑sighting authority.
This converter uses a widely accepted algorithm for approximate conversion. It is accurate for most dates but may differ slightly depending on regional moon sighting.
