Our Team
Hijri Guide is built and maintained by a dedicated team of Muslim developers, researchers, and Islamic knowledge specialists committed to providing accurate, accessible tools for Muslims worldwide.
Our Mission
Hijri Guide was created with a simple but important purpose: to help Muslims around the world stay connected to the Islamic calendar, prayer times, and religious observances — accurately and easily, regardless of where they live.
As Muslims living in diverse parts of the world, our team understands the challenge of tracking Hijri dates when the lunar calendar isn't part of everyday civil life. We built HijriGuide.com to solve this problem — combining modern technology with authentic Islamic knowledge.
Every tool on this site — from the Hijri calendar and date converter to the Qibla finder and prayer times calculator — is designed to be free, accurate, and genuinely useful. Our goal is to serve the global Muslim community with resources that are both technically reliable and rooted in sound Islamic principles.

Our Commitment to Accuracy
Authentic Islamic Sources
All Islamic content — rulings on prayer, fasting, Qibla, and calendar matters — references the Quran, authenticated hadith, and the established opinions of recognized Islamic scholars.
Multiple Calculation Methods
We support multiple prayer time calculation methods (ISNA, MWL, Umm al-Qura, Egyptian, Karachi, Tehran) to serve Muslims across different madhabs and geographic regions.
Transparent Limitations
We are clear about the limitations of calculated Islamic dates. Moon sighting may result in dates differing by 1-2 days. We always recommend verifying critical dates with your local mosque.
Regular Updates
Our tools and content are regularly reviewed and updated. Prayer time data is fetched in real time; calendar data is validated against trusted APIs daily.
Community Feedback
We actively welcome feedback from Muslim scholars, users, and community members. If you spot an error or have a suggestion, please contact us — accuracy is our highest priority.
No Religious Rulings
HijriGuide.com is an informational tool, not a religious authority. For matters of fiqh or official religious decisions, please consult qualified Islamic scholars.
