Prayer Times for Johnstone

Fajr in Johnstone today begins at the calculated true dawn time shown at the top of this page. This is based on Johnstone's exact coordinates (55.8°N, 4.5°W) and elevation of approximately 24 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 Johnstone gradually becomes earlier in summer and later in winter.

Maghrib in Johnstone 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 Johnstone, not a nearby city centre, ensuring higher local accuracy.

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

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

• Latitude (55.8°N)
• Longitude (4.5°W)
• Elevation (approximately 24 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 Johnstone, meaning results differ slightly from neighbouring towns.

Johnstone is located at 55.8°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 Johnstone may be close to other towns in Renfrewshire, 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 Johnstone may experience sunset slightly later than someone at lower ground level.
