How it works

Prayer times are calculated from the sun's position for your latitude, longitude, and date. With the ISNA method, Fajr begins when the sun is 15° below the horizon before sunrise, and Isha begins when the sun is 15° below the horizon after sunset. Sunrise and Maghrib are at 0.833° below the horizon (accounting for refraction), Dhuhr is at solar noon, and Asr is by shadow length (standard school, shadow factor 1). The calculation uses the same solar algorithm as our prayer time calculator, which was checked against a reference timetable to within 1 minute.

Please note: These are calculated times for the ISNA method. Local mosques may add a few minutes of caution or follow a different timetable. For congregational prayer, follow your local mosque.

Frequently asked questions

What is the ISNA prayer time method?

The ISNA method sets Fajr when the sun is 15 degrees below the horizon before sunrise, and Isha when the sun is 15 degrees below the horizon after sunset. It is the method of the Islamic Society of North America, and it is the standard most mosques in the United States and Canada use.

Why is ISNA Fajr later than other methods?

Because its angle is smaller. A smaller angle means the sun is less far below the horizon when Fajr begins, so Fajr comes later. In New York on 14 November 2026, ISNA Fajr is 05:23 while the MWL and Karachi methods give 05:07, a difference of 16 minutes.

Which cities does this support?

12 US cities (New York, Chicago, Houston, Los Angeles, Detroit, Washington DC, Dallas, Atlanta, San Francisco, Seattle, Boston and Philadelphia), plus Toronto, London and Karachi. For any other city, use our prayer time calculator and pick the ISNA method.

Do I need to adjust for daylight saving time?

No. Daylight saving is detected automatically using the US rule, from the second Sunday of March to the first Sunday of November. If your city does not observe daylight saving, untick the checkbox.

Are these times exact?

They are calculated astronomical times, accurate to within a few minutes for the method chosen. They are not a substitute for your local mosque timetable, especially for Fajr and Maghrib.
