About us & methodology
This page introduces our team and explains how every number on the site is produced, where the religious text comes from, and what we do when something is wrong.

The company
Hijri Calendar is a project of ICTSPS L.L.C (ICT Solutions & Professional Services), a company specialising in IT solutions and digital transformation, software, mobile app and website development, and business analytics and consulting, with offices in Tallinn, Estonia and Dubai, UAE.
Hijri dates
We use the Umm al-Qura calendar, the official calendar of Saudi Arabia, which is calculated astronomically in advance. We rely on its standard implementation built into browsers and operating systems (Unicode CLDR, the islamic-umalqura calendar), so the date you see here is the one Apple, Android and Windows devices show.
Many countries — Pakistan, Egypt and Morocco among them — start the month by sighting the new moon, so their month can begin a day earlier or later than Umm al-Qura. Our occasion pages point out that the actual date can differ by a day between countries; for fasting and Eid, follow the announcement of the official authority where you live.
Prayer times
Times are calculated astronomically from the sun's position for each day and city, using an algorithm adapted from the PrayTimes.org project (Hamid Zarrabi-Zadeh) under its free-use terms and ported to TypeScript.
Fajr and Isha depend on how far below the horizon each authority puts the sun, and each country has a default method on the site (table below). Asr follows the majority view (shadow equal to the object) by default; the Hanafi view (twice the object) can be selected in the settings. At high latitudes, Fajr and Isha are adjusted using the middle-of-the-night rule.
These are calculated times and can differ by a few minutes from your mosque's timetable or your country's official one, because of safety margins or rounding. Where they differ, follow your local mosque.

Qibla direction
We calculate the great-circle bearing from your location to the Kaaba (21.4225° N, 39.8262° E), in degrees from true north, and the distance with the haversine formula.
Phone compasses are affected by nearby metal and magnets; if the direction looks wrong, move the phone in a figure-of-eight to recalibrate it.
Zakat calculator
The nisab is 85 g of gold or 595 g of silver, and the amount due is one-fortieth (2.5%) once wealth reaches the nisab and a lunar year has passed over it.
Gold, silver and exchange rates are fetched automatically and can be edited by hand. The calculator is an aid for common cases; for complex wealth such as businesses, debts or property, ask a qualified scholar.
Supplications
Supplications are taken from the Quran and the authentic Sunnah — Sahih al-Bukhari, Sahih Muslim and the Sunan collections such as at-Tirmidhi — in the manner of Hisn al-Muslim.
Under every supplication we show its source: the surah and verse, or the hadith collection that narrates it. We do not knowingly include narrations graded weak; if you find one whose source looks wrong, tell us and we will review it.
Group khatma
A group khatma splits the thirty juz' among participants: each takes a juz, recites it aloud, then confirms it. The counter says "so many juz' completed", never "you completed the Quran"; names are optional and there is no leaderboard.
There is no field for a deceased person and no dedication of reward, because whether the reward of recitation reaches the dead is disputed between the schools, while supplication for them is agreed upon. The khatma's guidelines follow two fatwas:
Mistakes and corrections

Privacy
No tool on the site asks for an account, an email address or a phone number; only the contact form asks for your email, so that we can reply.
The khatma recognises you by a random code stored in your browser and on our server; it is not linked to your identity. Names are optional and visible to anyone who has the khatma link. When a khatma is created, your IP address is used briefly to limit abuse and is deleted within about two hours.
