Unlock the precision of time with House of Wisdom.

Experience a new standard in chronological accuracy. Developed by the House of Wisdom (Est. 1420 AH - 1999 AD), this application offers a sophisticated synchronization between Hijri and Gregorian calendars, rooted in decades of specialized astronomical research and mathematical lunar calculations.

Our work is guided by the divine precision established in the Holy Quran:

"They ask you, about the Moon Phases. Say, 'They are Dates for the mankind....'" (2:189)

"It is He who made the sun a shining light and the moon a derived light and determined for it phases - that you may know the number of years and it's account ..." (10:5)

"The sun and the moon by precise calculation." (55:5)

"Indeed, the number of months with Allah is twelve months in the register of Allah in the day He created the heavens and the earth..." (9:36)

The 100-Year Research Standard
Unlike standard calendar tools, our platform utilizes a verified 100-year research dataset spanning 1400–1500 AH. This ensures total synchronization with daily moon phases, providing users with the exact astronomical data required for research, religious observance, and historical tracking. By removing the "drift" found in standard algorithms, we provide a definitive reference for global date and timekeeping.
