Disclaimer
Prayer Times Global publishes calculated prayer times as a planning reference. This page sets out plainly what our figures are, what they are not, and where authority properly lies when our times and your mosque’s times disagree.

We are a reference, not a religious authority
The times on this site are produced by astronomical calculation using parameters published by recognised Islamic authorities. They are not a fatwa, a ruling, or an instruction. We do not issue religious opinions, we do not adjudicate between schools of jurisprudence, and nothing on this site should be read as guidance on how you ought to worship.
Your local mosque is the authority for your congregation. Where our times differ from the masjid you pray at, follow your mosque. Its timetable reflects decisions made by people with standing in your community and with knowledge of local circumstances we do not have.
Calculated times are not observed times
Every prayer time on this site is derived from the position of the sun for a set of coordinates on a given date. It is a mathematical prediction of when a sky condition will occur, not a record of someone observing that condition. The classical definitions of dawn and nightfall describe what an observer sees. Converting those descriptions into solar depression angles is an approximation that reputable authorities have made in different ways, which is why methods disagree.
Calculated times can also be affected by conditions no model accounts for: atmospheric refraction varying with temperature and pressure, dust and humidity, light pollution, and local terrain that raises or lowers the visible horizon.
Expect small differences from your mosque
A gap of a few minutes is normal and does not indicate an error. The usual causes are:
- Adhan versus iqamah. We publish the start of each prayer window. Mosques announce a later iqamah so the congregation can assemble. A gap of fifteen to twenty five minutes is routine.
- A different convention. Your mosque may follow an authority other than the national default we apply, which is common where a community has roots in another country.
- Precautionary minutes. Many mosques add a small safety margin to Fajr and Maghrib.
- Position within a city. We use one representative coordinate per city. Across a large metropolitan area true times vary by one to three minutes.
- Madhab. The Hanafi position places Asr substantially later than the Shafi’i, Maliki and Hanbali position. This is a difference of school, not an error.
Ramadan, fasting and time-critical worship
Our times include sunrise and Maghrib, which correspond to the boundaries commonly used for beginning and ending a fast. Please treat these with particular care.
Where fasting is concerned, small margins matter and the consequences of an error fall on you. We strongly recommend following the imsak and iftar times published by your local mosque or national authority during Ramadan rather than relying on this site alone. Many authorities publish a precautionary imsak some minutes before true dawn; we publish the calculated astronomical time and do not add that margin for you.
Moon sighting and Islamic dates
Our Hijri calendar tool performs an arithmetical conversion between the Islamic and Gregorian calendars. It is a mathematical convenience only.
It does not determine the start of any Islamic month. The beginning of Ramadan, the day of Eid al-Fitr, the day of Eid al-Adha, the Day of Arafah and other observances are fixed by moon sighting or by the announcement of the relevant authority in your country. Converted dates on this site may differ from the officially announced date by a day or more. Always follow the announcement of your national or local authority. We do not publish predictions in their place.
Qibla direction
Our qibla tool computes the great circle bearing from a given location to the Kaaba in Makkah. It is intended for orientation and planning. Its accuracy depends on the accuracy of the location supplied and, where a device compass is used, on that compass being properly calibrated and free from magnetic interference. Steel structures, electronic devices and vehicles all distort compass readings. For a permanent installation such as a mosque or a prayer room, use a surveyed bearing rather than a web tool.
High latitude locations
Above roughly 48 degrees of latitude there are periods each summer when the sun does not descend far enough below the horizon for astronomical dawn or nightfall to occur. In those conditions the standard angle model produces no valid Fajr or Isha time. Our figures fall back to a recognised approximation, and the resulting times are estimates rather than calculated values. Users at high latitude, including in the United Kingdom during June and July, should follow the position adopted by their local mosque or Islamic council.
Accuracy of city data
Each city carries stored coordinates, a timezone and a calculation method. We take care over these and correct errors when they are reported, but we do not warrant that every value is correct for every city at all times. Administrative boundaries change, timezone rules change, and a city’s dominant local practice may not match the national default we apply.
Availability and third party data
Prayer time calculations depend on an external astronomical service. We cache results so the site remains usable if that service is briefly unavailable, and we mark cached figures as such. We do not warrant uninterrupted or error free operation.
