Number Tools & Converters - Frequently Asked Questions
Why would I need a Hijri to Gregorian converter?
Many Islamic numerology calculations require a birth date in the Hijri (Islamic lunar) calendar. The converter lets you translate between the Hijri and Gregorian calendars accurately before running an Abjad or birth-date tool.
Can these tools be used with any tradition?
Yes. The utility tools - date converters, transliteration helpers, and cross-system comparisons - are designed to support work in every tradition covered on this site rather than belonging to a single one.
Are the converters accurate?
The date converters use standard astronomical and tabular algorithms. As with all calendar conversions there can be a one-day variance around month boundaries because the Islamic calendar depends on lunar sighting, which we note where relevant.
