Prayer Times for Ystrad Mynach

Fajr in Ystrad Mynach today begins at the calculated true dawn time shown at the top of this page. This is based on Ystrad Mynach's exact coordinates (51.6°N, 3.2°W) and elevation of approximately 123 metres above sea level. The timing is calculated using the MWL 18° method and automatically adjusted for Europe/London where applicable.

Because dawn shifts daily due to the Earth's tilt and orbit, Fajr in Ystrad Mynach gradually becomes earlier in summer and later in winter.

Maghrib in Ystrad Mynach begins at astronomical sunset — the moment the upper edge of the sun disappears below the horizon at your exact location. This time is calculated specifically for Ystrad Mynach, not a nearby city centre, ensuring higher local accuracy.

Even small differences in latitude, longitude, or elevation within Caerphilly can cause sunset to vary by several minutes.

Prayer times in Ystrad Mynach are calculated using precise astronomical algorithms that account for:

• Latitude (51.6°N)
• Longitude (3.2°W)
• Elevation (approximately 123 metres above sea level)
• Local timezone (Europe/London)
• Seasonal solar position

Fajr and Isha are determined using solar angles below the horizon, Dhuhr is based on true solar noon, Asr on shadow length, and Maghrib on sunset.

These calculations are location-specific to Ystrad Mynach, meaning results differ slightly from neighbouring towns.

Ystrad Mynach is located at 51.6°N latitude, which means daylight hours vary significantly between summer and winter.

In summer:

• Sunrise is earlier
• Sunset is later
• Fajr and Isha are further apart

In winter:

• Days are shorter
• Fajr is later
• Maghrib occurs earlier

This seasonal variation is caused by the Earth's axial tilt — not by changes in the calculation method.

Although Ystrad Mynach may be close to other towns in Caerphilly, even small differences in longitude can shift sunrise and sunset by approximately 4 minutes per degree.

Elevation also matters — someone in a higher part of Ystrad Mynach may experience sunset slightly later than someone at lower ground level.
