🇰🇪 Nairobi

Nairobi uses the Muslim World League method (method 3 in our calculator), an 18-degree Fajr and 17-degree Isha convention adopted by Jamia Mosque on Banda Street and by the Council of Imams and Preachers of Kenya as the default reference for the country's interior cities. The Supreme Council of Kenya Muslims (SUPKEM) coordinates broadly with the same standard, although coastal mosques in Mombasa and Lamu sometimes use slightly different angle conventions tied to East African tradition. The 18-degree Fajr angle behaves well at Nairobi's near-equatorial 1.3°S latitude, where twilight is short and predictable. Apps configured to Egyptian or Karachi will show Fajr and Isha drift by a few minutes from local mosque boards, while Dhuhr, Asr and Maghrib are unchanged because they depend on the sun's altitude rather than a twilight angle.

Prayer times in Nairobi shift very little across the year because the city sits almost exactly on the equator at 1.3°S, where day length stays close to twelve hours regardless of season. Fajr typically falls within a fifteen-minute band centred on 04:50 across the calendar, and Isha within a similar band centred on 19:25. Sunrise and sunset both vary by less than thirty minutes between solstices, the smallest range of any city in this batch and a useful contrast with high-latitude capitals like London or Moscow. The two rainy seasons — the long rains in March to May and the short rains in October and November — bring heavy cloud cover that makes adhan-by-eye difficult, but the calculated times themselves are otherwise extremely stable. Nairobi's 1,795-metre altitude on the Kenyan highlands makes Fajr air notably cool throughout the year regardless of season, even though the city sits in the tropics.

Nairobi has a substantial Muslim community, estimated at around ten percent of the city's population — the highest share of any Kenyan city outside the coast and the north-east. The community is internally diverse: Swahili-coast traders who moved inland in the colonial era, South-Asian-heritage families descended from the Indian Ocean trade routes, and a large Somali-Kenyan population concentrated in Eastleigh, sometimes called Little Mogadishu for its dense business and cultural ties to the Somali community across the wider region. The Friday congregation at Jamia Mosque on Banda Street pulls worshippers across all four Sunni schools — Shafi, Hanafi, Maliki and Hanbali — alongside a smaller Shia and Ismaili presence. The mosque's medical clinic, library and welfare network are anchors of the wider community. Nationally, Kenya is roughly eleven percent Muslim, with the largest concentrations along the coast at Mombasa and Lamu and in Garissa and the north-east near the Somali border.

Jamia Mosque on Banda Street in the Nairobi Central Business District is the principal Friday gathering point in the Kenyan capital, with three silver minarets and a white marble facade that has anchored the city's Muslim life since the building opened in 1925. Friday congregations regularly fill the prayer hall and overflow into the adjoining courtyard, drawing worshippers from across the Sunni schools — Shafi, Hanafi, Maliki and Hanbali — and a smaller Shia presence. The Eastleigh Sixth Street Mosque is the second-largest Friday gathering and the central mosque for the Somali-Kenyan community. Sir Ali Muslim Club Mosque and Masjid Riyadha in South C handle smaller neighbourhood congregations. Khutbas at Jamia are typically delivered in Arabic with English and Swahili summaries, and Friday prayer usually begins between 12:30 and 13:00.

Prayer times differ between cities because they are calculated from the apparent position of the sun, which depends on a city's latitude, longitude and the date. Nairobi sits at 1.3°S, 36.82°E in the Africa/Nairobi time zone, almost on the equator, so its day length stays close to twelve hours all year and its twilight unfolds quickly compared with cities far from the equator. Two cities at very different latitudes — say Moscow at 55°N and Nairobi at 1.3°S — see Fajr and Isha sit in completely different relationships to the calendar, with Moscow swinging widely between solstices and requiring high-latitude adjustment in summer, while Nairobi barely shifts at all from one season to the next. Even cities at similar latitudes diverge if they fall in different time zones or follow different calculation conventions for the Fajr and Isha twilight angles.
