JAKIM Prayers Time

[farisfaisalthena]

Just a question, would it be possible if I send you the source code of the api i used for JAKIM? I used to use an api to get the accurate prayers time but its slow so thats why I switch to this library. If it would be helpful to integrate JAKIM method do let me know as I would send the source code on GitHub

Yes would love to see it. As long as its doing calculation and not just using a fixed timetable that would be extremely helpful.

https://github.com/kayrules/solatjakim-api-site. not sure if this is helpful but i will find more if there nothing here

[z3bi]

It looks like this is just downloading the prayer times from e-solat.gov.my. Sorry but for this library we are focusing on calculation based approaches.

[farisfaisalthena]

Can I know what kind of calculation is required because i did some findings and found this https://www.qiblaplus.com/prayertimes.html but not sure how helpful it is

[z3bi]

This appears to be what we already do.

As discussed in #43 now that we have added the updated rounding, you should have accurate JAKIM prayer times. If you want to match the government issued timetable you just need to use the same coordinates they use. Is there anything else you're looking for?

[farisfaisalthena]

Because the times are not accurate especially for Subuh. Please note that the left is from JAKIm and right is from the library. Although as mentioned before that mostly is just one or two minutes early, I have received a few feedback saying that having a accurate time is ideal as the app will be relied on if a particular user goes to a new place and does not know the time. I have also tested the coordinates from the compiled locations below

Subuh - 5:53 AM - 5:43 AM -> 10 Minutes Early
Zohor - 1:19 AM - 1:18 PM -> 1 Minute Early
Asar - 4:45 PM - 4:44 PM -> 1 Minute Early
Maghrib - 7:28 PM - 7:26 PM -> 2 Minutes Early
Isyak - 8.44 PM - 8:42 PM -> 2 Minutes Early

Because as alternative if the detection of current location coordinates does not work i will let users choose this location above and use the coordinates if its accurate also

Does this library produce times closer to the published times you are comparing against?

[farisfaisalthena]

Actually for this particular one i have not tested but if you want to test this after implementing like that I could help you

[z3bi]

For the 10 minute difference in subuh that is because they appear to be using Imsak as the Fajr time? It seems though you can just add 10 minutes to replicate their subuh time.

Aside from that, differences of 1-2 minutes is almost unavoidable. Published timetable used by governments are often "hand tweaked" and can't be replicated by calculation alone.

As an app developer you can either offer location specific times that use calculations (more accurate) or you can choose to present published timetables. Asking a calculation library to replicate a timetable exactly is simply not feasible. It seems perhaps you simply want to offer the exact timetable published by the Malaysian government and that is not something this library will have as a feature.

[farisfaisalthena]

location specific times that use calculations(more accurate)

You mean provide like list of location with their coordinates instead of automatically using their current location right?

[korbav]

@farisfaisalthena Are you located in Malaysia?
If so, could you confirm (or not) whether JAKIM is only used in Malaysia (or is it also used in other countries like Indonesia)?
If it's only used in Malaysia, and because the areas definition is fixed and finite, then referring to the sandbox I did some days ago, it might be a good to reconsider its implementation https://codesandbox.io/s/wild-voice-xo7fd.

However, there's a big warning even if we'd dive into that, as said @z3bi , and also as explicitly written in https://www.e-solat.gov.my :

Which means that, potentially, there are as many tweaks/slightly different calculation methods as the number of states in Malaysia, it's clearly impossible to be 100% accurate, and even if we would, there would be no guarantee to stay sync over the time (for example if a mufti would be replaced by another one who would change the state's calculation method).

[farisfaisalthena]

@korbav hi yeah im located in malaysia. I am also sure that JAKIM is also used in Indonesia https://www.muslimpro.com/Prayer-times-Indonesia-ID?date=&convention=JAKIM

[korbav]

@korbav hi yeah im located in malaysia. I am also sure that JAKIM is also used in Indonesia https://www.muslimpro.com/Prayer-times-Indonesia-ID?date=&convention=JAKIM

Great, I think at this point, we need to collect verified information about what is happening behind the scene with the calculations, how is it being spread over the different countries, which areas are concerned, what kind of tweaks are being done etc..

From my perspective, the most benefical now is that you contact directly JAKIM institute (in Malay) to get strong information/documents we can base ourselves on.

After that, we will be able to have a better analyzis and to take a decision if there is an interest / a possibility / a pertinency to implement something.

[farisfaisalthena]

From my perspective, the most benefical now is that you contact directly JAKIM institute (in Malay) to get strong information/documents we can base ourselves on.

Sure thing! Would it be possible if you let me know the questions you need so I dont miss any questions or another option I can provide you the email of JAKIM

[farisfaisalthena]

I did tested it but unfortunately the time gets earlier compared to the current implementation

I would say (it's also necessary to wait the input of @z3bi which will be more concise!) :

• In which countries is JAKIM method being used?
• Is JAKIM method being used the same way wherever it's used (ie. in all the countries where it's used) ?
• Are the geographical areas defined by the JAKIM fixed or subject to change?
• Which degrees of liberty are given to the states using this method? (ie. what kind of choices are left to the muftis?)
• Do we have a clear list of the tweaks in the different states? is it subject to change over the time / mufti replacements?
• Can we have a technical documentation of the algorithm/parameters being used?
• /Or Can we have a concise overview of the method?

That's it for me, I don't see anything else but please also wait for @z3bi 's input before contacting JAKIM.

No, calculating based on the user's exact coordinates are more accurate Islamically even if they are different from the published timetables. Consider that the government needs to provide a prayer time for an entire city, but on the eastern part of the city the sun sets at 5:01 PM and on the western side of the city the sun sets at 5:02 PM. The government might publish 5:02 PM for the entire city, but actually for people on the eastern side thats not the actual time of sunset.

These are the kinds of tweaks that the government is doing by hand that we may simply never be able to replicate in any kind of calculation.

[z3bi]

In terms of contacting JAKIM, any official explanation on how they arrive at their prayer times would be a good starting point. Once we have that I think we can decide from there.
