How Asr Time Is Calculated
How shadow length affects Asr time in standard and Hanafi calculation settings.
Asr time is connected to shadow length after solar noon. The standard setting begins Asr at one shadow measure, while the Hanafi setting uses a longer shadow and can make Asr later.
If two calendars show different Asr times for the same city, the Asr setting is one of the first things to check.
Reading the Asr Setting
Check whether the timetable uses standard or Hanafi Asr, then check city, timezone, and calculation method.
