Bangladesh prayer times

The Islamic Foundation sets prayer times in Bangladesh through a Dhaka reference table and a list of district corrections. This page explains what the app calculates instead, and where one published Islamic Foundation timetable can be selected directly.

Scope of this claim

The Islamic Foundation publishes prayer timetables in Bangladesh, but the app does not serve that national table country-wide; the Islamic Foundation’s published timetable can be selected in the app as an institutional source, described below. Everywhere else the times are calculated with the University of Islamic Sciences, Karachi method — the convention Bangladeshi timetables are themselves built on. A calculation cannot reproduce every district correction or every mosque’s precaution margin, so this page makes no “0-minute difference” statement; a local card can still sit a minute or two away.

Cities are listed by population. A city that is missing has no entry in the prayer-times database yet.

Calculation and source

Institution: Islamic Foundation Bangladesh
Method: Karachi method; Fajr 18°, Isha 18° — a calculation, except where the Islamic Foundation’s published timetable is selected.
Asr: Asr defaults to the Hanafi shadow ratio of two, which is what Bangladeshi timetables print almost without exception; the ratio can be changed in the app and only Asr moves.
Precaution minutes: None. The app adds no precaution minutes of its own. Printed Bangladeshi cards commonly do add their own margin.
Time zone: Bangladesh has not used daylight saving since the short-lived experiment of 2009–2010, so nothing in these tables shifts because of a clock change. The country is compact enough that the east–west spread between Sylhet and Khulna is modest, but it is real, and each city page is calculated from its own coordinates rather than from Dhaka.
Hijri calendar and crescent: Ramadan, Eid and the other Hijri dates are announced by the National Moon Sighting Committee, which meets at the Islamic Foundation in Dhaka. A small number of communities — the Mirzakhil and Shah Sufi Darbar congregations among them — follow Saudi announcements and begin a day earlier; the app follows the national committee.

The state religious body. It publishes a Dhaka reference timetable together with a table of district corrections, and hosts the national moon-sighting committee. The app can serve one of its published timetables as a selectable source and calculates elsewhere.

How prayer times are set in Bangladesh

The Islamic Foundation, the state religious body, is the closest thing Bangladesh has to a prayer-time authority. It publishes a reference timetable for Dhaka together with a table of district corrections — a list of how many minutes to add or subtract for each of the other districts — and local mosques print their cards from that. It is a genuine national system, but it is a two-part one, and the app does not yet reproduce it country-wide. What the app serves for most Bangladeshi cities is a direct calculation from the city’s own coordinates, using the fajr and isha convention those Bangladeshi timetables are themselves built on.

The Islamic Foundation timetable

One Islamic Foundation office publishes a perpetual timetable — one row for each day of the year, valid from year to year — and that table is integrated into the app as a selectable source. When you choose it, the times you see are the institution’s own published minutes rather than a calculation; days the perpetual table does not cover fall back to the calculation.

Asr, Fajr and where gaps come from

Bangladeshi timetables use the Hanafi shadow ratio for Asr essentially without exception, and these pages follow that. The fajr and isha angles in common use are the eighteen-degree pair associated with the University of Islamic Sciences in Karachi, which is what the calculation here uses. Where you do see a gap against a printed card, look first at precaution minutes: the Islamic Foundation’s own practice, and the habit of most local printers, is to publish Fajr a touch early and Maghrib a touch late. Those margins are intentional, and they are not reproduced here.

Which cities have a page

The Bangladeshi cities listed here, from Dhaka and Chattogram to Sylhet, Rangpur, Khulna and Barishal, are the locations in the app’s prayer-times database; this hub lists what exists rather than inventing entries. Each page is calculated from its own coordinates rather than offset from Dhaka; if your town is not listed, choose the nearest one in the same district.

Questions

Can I get the Islamic Foundation’s own times?

Yes, where the Islamic Foundation’s published timetable is available as a source: select it in the app’s prayer-time settings and the times shown are the institution’s own published minutes. Elsewhere in Bangladesh the times are calculated with the Karachi method.

Why does my local card show Fajr a minute or two earlier?

Almost always a precaution margin. Bangladeshi printers routinely publish Fajr slightly early and Maghrib slightly late; the underlying calculation is usually identical to the one used here.

Which Asr does Bangladesh use?

The Hanafi shadow ratio of two, which is what Bangladeshi timetables print. You can switch to the ratio of one in the app and only Asr moves.
