meezaan Thanks, this was my bad (also put the wrong year on MuslimPro 🙂). However, is it possible to add resources to the API or at least on the website to inform the end users where actually all these parameters (including isha and fajr angle) come from? For example, you say "according to Umm Al Qura", I can't read Arabic (but I can use a translator for sure), but if they share their calculation methods and details, seeing those links would clarify a lot of things in my opinion.
