🇨🇳 Beijing

Beijing uses the Muslim World League method (method 3 in our calculator), an 18° Fajr and 17° Isha convention adopted as a balanced default by the city's Hui mosque administrations including Niujie, Dongsi and Madian. China has no nationwide Islamic authority that fixes a single calculation method, so individual mosque committees and the Islamic Association of China have settled on MWL because it produces reasonable values at Beijing's 39.9°N latitude without the overly late Isha that 19.5° conventions yield in summer. Niujie Mosque, founded in 996 CE during the Liao dynasty, prints its monthly schedule on this basis and most Beijing prayer-time apps mirror that timetable. Worshippers arriving from Saudi Arabia, Egypt or South Asia and using their home country's method will see Fajr and Isha drift by a few minutes, while Dhuhr, Asr and Maghrib remain identical because those depend on the sun's transit and altitude rather than the twilight angle.

Prayer times in Beijing shift most between the summer and winter solstices because the city sits at 39.9°N, far enough from the equator to produce a clear day-length contrast. In late June, Fajr is called before 03:30 and Isha after 20:45, stretching the daylight fast in Ramadan to roughly sixteen hours when the month falls in summer. By late December the pattern inverts sharply: sunrise slips past 07:30, Maghrib arrives before 17:00 and the entire span of obligatory prayers compresses into under ten daylight hours, made colder by the dry continental winter. The equinoxes in March and September are the smoothest periods, when daily times shift by only a minute or two. Beijing's pollution and dust events occasionally make horizon observation difficult, so mosques rely entirely on calculated tables rather than visual confirmation, and Niujie publishes a fresh schedule each month.

Beijing hosts long-established Hui and Uyghur communities along with foreign Muslim residents, students and diplomats, totalling roughly 250,000–300,000 Muslims across the wider metropolitan area according to community estimates. The Hui — Mandarin-speaking Muslims of mixed Chinese and Central Asian descent — have lived in the city for over a thousand years, with their demographic core in the Niujie neighbourhood of Xicheng district, where halal butchers, restaurants and bookshops cluster around the historic mosque. Uyghur residents, mostly migrants from Xinjiang, are present in smaller numbers across Haidian and other districts. The Islamic Association of China, headquartered in Beijing, coordinates national religious affairs and operates the China Islamic Institute training imams. Foreign Muslims include diplomats, business travellers and students at universities such as Peking and Tsinghua, with several embassies maintaining their own prayer rooms for staff and residents.

Niujie Mosque in Xicheng district hosts the largest and most historic Friday prayer in Beijing, drawing both local Hui worshippers and visiting Muslims from across the city. Founded in 996 CE during the Liao dynasty and rebuilt several times under the Ming and Qing emperors, the mosque blends Chinese hall-and-courtyard architecture — sloped tile roofs, painted wooden beams, a pagoda-style minaret — with Arabic calligraphy on the prayer hall walls. It seats well over a thousand worshippers and is the de facto principal mosque of the capital. Dongsi Mosque in Dongcheng district, also Ming-era, is the second-busiest Friday congregation, with Madian Mosque and Haidian Mosque serving the northern and university districts. Khutbas are typically delivered in Mandarin, occasionally with Arabic recitation, and most start between 12:30 and 13:00 to accommodate the standard Chinese workday.

Prayer times differ between cities because they are derived from the apparent position of the sun, which depends on each city's latitude, longitude and the date. Beijing sits at 39.9°N, 116.4°E in the Asia/Shanghai time zone, so its sunrise, solar noon, sunset and twilight angles produce a daily timetable that no other city shares exactly. Two cities at very different latitudes — say London at 51°N and Riyadh at 24°N — experience twilight over different durations, so Fajr, Maghrib and Isha can sit hours apart even on the same calendar date. Even cities at similar latitudes drift if they sit in different time zones or follow different calculation conventions for the Fajr and Isha twilight depression angles. China uses a single nationwide time zone despite spanning roughly five geographic ones, which adds another layer of variation between Beijing and far-western cities like Urumqi.
