Assalamu alaikum,

Please add the unified prayer timetable used by Muslim organisations in the Czech Republic, published at:

https://islamweb.cz/casy/casy.php

The timetable is based on the France/UOMF 12°/12° method, but it uses fixed reference coordinates and local calculation parameters. Therefore, Pillars prayer times do not always match it, and fixed manual minute adjustments do not work across different dates.

A similar feature is already planned for the unified London prayer timetable. It would be very helpful to add a Czech Republic / Prague timetable preset as well.

Reference location for Prague:
Latitude: 50.08° N
Longitude: 14.42° E
Altitude: 259 m
Fajr angle: 12°
Isha angle: 12°
Asr: Standard

This official timetable is widely used by Muslims in the Czech Republic.

Jazakum Allahu khairan.
