Why we made it

Getting a household ready for Ramadan usually means three or four things that do not talk to each other: a timetable from one website, a printable chart bought for each child, a reading plan worked out on the back of an envelope, and a notes app for guests and charity days. We put them in one place, made them agree with each other, and made the result print well on A4 or US Letter.

What it does

It calculates suhoor, iftar and every prayer time for each day of the month from the position of the sun, by the method you choose, and names that method on everything it prints. It makes a fasting tracker and a good-deed chart for up to 6 children, with their names in any script. It shares the 604 pages of the Quran, or a juz a day, across the people reading. The rules are all written out on how the times are worked out.

What it is not

Times are calculated; follow your local mosque for the start of the month and for prayer times.

Where the data comes from

The city list, about 3,000 cities with their coordinates and time zones, is drawn from GeoNames (geonames.org) and used under the Creative Commons Attribution 4.0 licence; we chose the cities and rounded the coordinates. The expected start of each month comes from the Umm al-Qura calendar as carried in the Unicode calendar data. The sun's position follows Jean Meeus, Astronomical Algorithms. Our tests hold the times to published values for five cities on five dates, within 2 minutes.
