Private, explicit calculation
Prayer Times Calculator
Calculate prayer-time estimates using an optional one-time browser location request, a city you select, or coordinates you enter manually. Your calculation method, Asr method, high-latitude rule, date, and UTC offset remain explicit.
This page requests browser location only after you press the current-location button. Otherwise, no location request occurs.
Browser coordinates, manually entered values, date, and settings remain only in current page memory and clear on refresh, Reset, or when you clear or replace the location.
Prayer-form values are not added to the URL, stored as preferences, or sent to an external prayer-time, map, geocoding, or timezone provider.
What this tool does
Calculates prayer-time estimates for a location and date you choose, keeping every convention that affects the result — calculation method, Asr method, high-latitude rule, and UTC offset — visible and explicitly selected rather than guessed.
When to use it
- You are travelling and want an estimate for somewhere your usual timetable does not cover.
- You want to see how much the times shift when the calculation method or Asr convention changes.
- You need a reference for planning rather than a substitute for your local mosque's timetable.
How the figure is produced
- You supply a location — a one-time browser location request, a city from the list, or coordinates typed in by hand — plus a date and a UTC offset.
- A calculation method sets the solar angles used for Fajr and Isha. Ten are supported, including Muslim World League, Umm al-Qura, Egypt, Karachi, ISNA, Moonsighting Committee, Dubai, Qatar, Kuwait, and a custom option.
- The Asr method sets the shadow-factor convention: Standard (single shadow length) or Hanafi (double).
- A high-latitude rule — Middle of Night, One Seventh, Twilight Angle, or None — governs what happens where twilight does not end, so Fajr and Isha remain defined far from the equator.
Worked example
Someone compares the two Asr conventions for the same location, date, and calculation method, changing nothing else.
- Calculation method
- Unchanged between the two runs
- Asr — Standard
- Shadow equal to object length plus noon shadow
- Asr — Hanafi
- Shadow equal to twice object length plus noon shadow
- Effect on Asr
- Hanafi falls later, commonly by around an hour
- Effect on Fajr, Dhuhr, Maghrib, Isha
- None — the Asr convention affects Asr only
This is why two reliable timetables for the same city can disagree on Asr while matching on every other prayer. Check which convention your timetable follows before treating a difference as an error.
Assumptions built in
- Times are astronomical estimates for the coordinates and date you supplied, at sea level.
- The UTC offset you select is applied as given. Daylight-saving transitions are not detected for you, so an offset that was right last month may not be right today.
- The angles attached to each named method are the conventional published ones for that method; the tool applies them rather than deciding which is correct for you.
Limitations
- Local timetables commonly differ from a pure calculation. Mosques apply their own precautionary margins, and a congregation time is a decision rather than an astronomical fact.
- Elevation, local horizon, and atmospheric conditions are not modelled, and each can shift sunrise and sunset noticeably in hilly or hazy locations.
- High-latitude locations are genuinely contested. Where twilight never ends, the rule you pick determines the answer, and no rule is presented here as the correct one.
- Nothing is stored. Location is used for the calculation in your browser and is not transmitted to or retained by this site.
How this differs from the related tools
- Islamic Calendar
Handles Hijri dates rather than daily times, and is likewise a calculation rather than an observation.
- Ramadan Hub
Covers fasting-related planning, where Fajr and Maghrib matter most and local confirmation matters more than usual.
