Diffrent prayer times in Diyanet method

raymenstereo

Selam aleykum,
i have a problem that fajr and isha timings are far away from the timings from Diyanet API. Is there any reason? Better solution than tuning? For couple of minutes i can use the tune option but it is over 40 min diffrence.

AlAdhanAPI:
"timings": {
"Fajr": "03:00",
"Sunrise": "05:15",
"Dhuhr": "13:31",
"Asr": "17:48",
"Sunset": "21:37",
"Maghrib": "21:37",
"Isha": "23:44",
"Imsak": "02:50",
"Midnight": "01:26",
"Firstthird": "00:08",
"Lastthird": "02:45"
},

Diyanet API:
{
...
"fajr": "03:42",
"sunrise": "05:15",
"dhuhr": "13:31",
"asr": "17:48",
"maghrib": "21:37",
"isha": "22:59",
"astronomicalSunset": "21:30",
"astronomicalSunrise": "05:22",
"hijriDateShort": "28.11.1446",
"hijriDateShortIso8601": null,
"hijriDateLong": "28 Zilkade 1446",
"hijriDateLongIso8601": null,
"qiblaTime": "11:17",
"gregorianDateShort": "26.05.2025",
...
}

raymenstereo What location is this for? Can you share the actual API query?

The Diyanet method is expermental because Diyanet does not actually share the calculation (like UAE Awqaf, for instance). Applying the method, therefore, to areas outside Turkey might result in a massive variance.

The angles currently in use are the older Ottoman method that was last used by Diyanet up to the 90s if I'm not mistaken.

Still happy to investigate the 40 min variance - have never come across something so drastic.

For the location Hamm in Germany, I used the following request to get the prayer times:
http://api.aladhan.com/timingsByCity/26-05-2025?city=Hamm&country=DE&state=NW&method=13&calendarMethod=DIYANET&x7xapikey=X.

Unfortunately, they don’t provide that specific information. This difference mainly appeared during summer time. In winter, the difference wasn’t as significant.
