Please read this disclaimer carefully before relying on any date conversion results provided by GPTStand.
Hijri dates are inherently subject to regional variation based on actual moon sighting. Our results use astronomical calculation and may differ from officially announced dates by ±1 day.
The Hijri–Gregorian date conversion results provided by GPTStand are intended for general informational and reference purposes only. While we strive for the highest level of accuracy using established astronomical calculation methods, the results should not be used as the sole basis for legal, official, governmental, or religious decisions.
The Islamic (Hijri) calendar is a lunar calendar in which months begin with the sighting of the crescent moon. Because actual moon visibility depends on geographic location, atmospheric conditions, and local religious authority decisions, the start of any given Hijri month may vary by one or more days between countries and regions.
GPTStand uses a standardized astronomical calculation method based on established mathematical formulae. Results are designed to align with the Umm Al-Qura calendar of Saudi Arabia wherever possible, but a discrepancy of ±1 day is inherent to the nature of the Islamic calendar and is explicitly acknowledged on all result outputs.
For legal documents, passport applications, official government records, court filings, or any purpose requiring a certified Hijri date, you must consult the relevant official government authority or religious council in your country. GPTStand cannot guarantee that its conversion results match any specific official calendar publication.
GPTStand is provided on an "as is" and "as available" basis without any warranties of any kind, either express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, or non-infringement.
