The Earth's Tilt and Orbit
If you check your prayer timetable, you'll notice the times shift by 1 or 2 minutes every day. This happens because the Earth orbits the sun on an elliptical path and is tilted on its axis at approximately 23.5 degrees.
As the Earth moves through the seasons, the apparent path of the sun across the sky shifts. In summer, the sun reaches higher altitudes, making days longer (earlier Fajr, later Maghrib). In winter, the sun stays lower, creating shorter days.
The Role of Latitude and Longitude
- Latitude (North/South): Determines the length of your day. Cities further north (like Islamabad) experience more extreme seasonal shifts in Fajr and Maghrib times compared to cities closer to the equator (like Dubai).
- Longitude (East/West): Determines exactly when solar noon occurs. A city further east will experience all its prayer times earlier in the day than a city further west, even if they are on the exact same latitude.
