Prayer time apps: why times differ

Two apps differ because they use different rules, not because one is broken. Match the method and the Asr setting to the times you use at home, and keep them for the whole trip. This guide shows what to check and how to line your app up with the times from JAKIM (the Department of Islamic Development Malaysia).

Why do apps disagree?

Cause	What it changes	What to do
Calculation method	The angles for Subuh and Isyak	Choose the method that matches your Malaysian source
Asr setting	When Asr starts	Match the school you follow at home
Adjustments	Minutes added or taken off each prayer	Set them to zero first, then compare
Location	Times shift with the city	Update the city after landing

The method is the first thing to check. A gap of a few minutes at Subuh and Isyak points to it, while a gap of a whole hour points to a wrong location or time zone.

How do you match JAKIM’s times?

Do this at home, before you travel.

• Open the app and set your Malaysian town as the location.
• Look up JAKIM’s times for your zone on the same day.
• Compare each prayer, then change the method, then the Asr setting, then the adjustments, one at a time.
• Stop when the app matches JAKIM, then save or screenshot the settings.

On the trip, change only the location. Keep the other settings as they are, so you are using the same rule as at home.

Does the time zone change?

Your phone clock may change, so be sure the app is following it. South Korea is one hour ahead of Malaysia¹, while Thailand² and Vietnam³ are one hour behind. Taiwan shares Malaysia’s time⁴.

Even where the clock matches, your prayer times will not, because they follow the city. After landing, update the location and check the date.

What if the local mosque disagrees?

A mosque may use a different method, and that is normal. Both can be sound. If the gap is a few minutes, ask a staff member or your ustaz which to follow. If you plan to combine prayers while travelling, ask your ustaz or your state mufti office what applies to you.

For your own planning, work from your matched settings and keep a small margin so you are not rushing the end of a window.

What other checks help?

• Compare two apps once on the first day, to confirm they agree.
• Keep the app updated, but not during a trip day, in case settings reset.
• Turn on notifications for each prayer, and test them at home.
• Save the times offline in case you have no signal at the sight.
• Do not use an old screenshot from a different city.

Your next step

Once your settings are matched, mark each day’s prayers on the prayer-stop itinerary checklist. To see how the day fits around them, read how to plan sightseeing around five daily prayers. If you are heading abroad for the first time, choosing a first overseas holiday as a Muslim Malaysian helps with the wider decisions, and the Prayer and daily pacing hub gathers the rest.
