Austria prayer times

Austria is one of the few European countries with a legally recognised Islamic religious body that publishes its own unified prayer timetable. The times shown come from the timetable Diyanet publishes for Austria; this page explains both tables and how they relate.

Calculation and source

Institution
Islamic Religious Community in Austria
Method
Diyanet
The timetable Diyanet publishes for Austrian settlements (fajr 18° / isha 17°, the criteria agreed at the 2021 Istanbul congress on unifying prayer times — the same criteria IGGÖ cites for its own table).
Asr
IGGÖ defines the afternoon prayer explicitly at a shadow ratio of one, giving as its reason the position of the majority of scholars. The app’s Austrian default was corrected to match that definition; the Hanafi time remains available as a setting.
Precaution minutes
None. The app adds no precaution minutes of its own.
Time zone
Austria follows the European daylight saving schedule. The country runs about six degrees of longitude, so sunset in Bregenz on Lake Constance arrives roughly twenty minutes later by the clock than in Vienna on the same evening.
Hijri calendar and crescent
IGGÖ announces the start of Ramadan and the two Eids for Austria, and as the recognised body its announcement carries across the mosque communities more consistently than in neighbouring countries.

The legally recognised representative body for Muslims in Austria under the Islam Act of 2015; it has published unified national prayer times since 2023.

Austria prayer times

An unusual European case

Most European countries in this directory have no Islamic body with the standing to publish a national prayer timetable. Austria does. The Islamic Religious Community in Austria has been a legally recognised religious society since the Islam Act, and in that capacity it publishes unified Gebetszeiten for the country. The unification took effect on 1 January 2023 and ended a period in which Turkish, Bosnian, Arab and Chechen congregations in Vienna printed different times for the same day. When a page in this directory talks about a country “having” a timetable, Austria is what that looks like.

Why the afternoon prayer moved

The most consequential detail in the IGGÖ table is its definition of the afternoon prayer. The institution states explicitly that Asr begins when an object’s shadow equals its own length plus the midday shadow — the shadow-one ratio — and gives as its reason the position of the majority of scholars. The app previously assumed that Austria, with its large Turkish-origin community, would follow the Hanafi shadow-two definition. That assumption was corrected not by a measurement but by the institution’s own published text. The difference is large: at Vienna’s latitude in late June the two definitions are more than an hour apart, and the earlier of the two is the one Austria publishes.

What the app shows for Austrian cities

The city pages below show the timetable Diyanet publishes for Austrian settlements, and every row names it as the source. Thirty Austrian cities were checked line by line against Diyanet’s own pages and all six times matched in all thirty; when that timetable is selected in the app, the times shown match it with a 0-minute difference. The table follows fajr at eighteen degrees and isha at seventeen — the criteria of the 2021 Istanbul congress, which is the same reference IGGÖ cites for its own work — with the shadow-one afternoon that IGGÖ defines. No claim of a match with the IGGÖ table is made on this page, and none should be inferred from the fact that the two share a starting point.

Nine cities and the rest of the country

The IGGÖ table covers nine Austrian cities, while the list below runs to thirty, from Vienna down to Bludenz. That gap is worth keeping in mind when comparing. Austria is mountainous, and the same caution that applies in Switzerland applies in Tyrol and Vorarlberg: a printed maghrib is calculated for a level horizon, and in a valley below the Alps the sun disappears behind a ridge well before that time. In Innsbruck, Feldkirch and Bregenz the visible sunset and the printed one can be separated by a long interval in winter.

Questions

Does Austria have an official prayer timetable?
Yes. IGGÖ, the legally recognised Islamic religious community, has published unified national prayer times since 2023. The app does not serve that table; the match claim on this page refers to the timetable Diyanet publishes for Austria.
Why does the app show an earlier afternoon prayer than a Turkish calendar?
Because IGGÖ defines Asr at a shadow ratio of one, while the Turkish table uses two. The app follows the Austrian definition for Austria. At Vienna’s latitude the two are more than an hour apart at midsummer.
Why is the sun gone before maghrib in the mountains?
Prayer timetables are calculated for a level horizon. In an Alpine valley the sun sets behind a ridge earlier than it reaches that horizon. Every published calendar works the same way; the printed time is the astronomical one.
