Methodology
Namaz times use the University of Islamic Sciences, Karachi method: Fajr at 18 degrees and Isha at 18 degrees. Asr defaults to the Hanafi shadow factor of 2. A Shafi, Maliki or Hanbali choice changes only Asr, to factor 1. All clocks are Indian Standard Time, Asia/Kolkata, which does not use daylight saving.
Times on the page
The five prayers are Fajr, Zuhr, Asr, Maghrib and Isha. Sunrise is shown because sehri and Ishraq depend on it. Ishraq is sunrise plus 20 minutes. Chasht is the midpoint from sunrise to Zuhr. Neither is one of the five prayers.
Calculated times are not a masjid jamaat chart. Many masjids add a few minutes as ihtiyat. A personal offset stays on your device and does not change the published time.
Hijri and Ramadan
The Hijri date starts from the Umm al-Qura calendar, then applies the India offset in the calendar file, usually minus one day. India can differ from Saudi Arabia. Ramadan and both Eids carry the expected Gregorian dates and stay labelled until a moon-sighting body in India confirms them.
Cities, zakat, drafts
Fifty city centres are published. This is not yet the full list of Indian cities over 50,000 people. Zakat uses 2.5 percent, 87.48 grams of gold or 612.36 grams of silver, and it does not ship a gold price. Pages marked draft are left out of the build.
Questions people ask
Which calculation method is used?
University of Islamic Sciences, Karachi. In adhan-js that is CalculationMethod.Karachi(). On Aladhan it is method 1.
Does the school toggle move Fajr?
No. Only Asr changes. Hanafi uses shadow factor 2. Shafi, Maliki and Hanbali use factor 1.
Why can the Hijri date differ from Makkah?
Moon sighting in India is often a day after the Umm al-Qura date. The offset is an admin setting, not a claim that one side is wrong.
Are the city coordinates from a census file?
They are common city-centre values, hand-checked for these fifty. GeoNames is credited for the wider list when that import is added. Populations are rounded sorting figures, not a live census.
