Prayer Times in Boston.

About the ISNA calculation method

The Islamic Society of North America (ISNA) method is the standard for prayer times across the US and Canada. It sets both Fajr and Isha at 15 degrees below the horizon, a slightly shallower angle than the Muslim World League uses in Europe. That choice keeps Fajr and Isha at reasonable clock times for cities at Boston's latitude, where deep twilight angles would otherwise push the times to extremes in summer.

Most masjids in Greater Boston, including the Islamic Society of Boston Cultural Center, publish their daily timetables on the ISNA angle. FivePrayer auto-detects your location and applies ISNA for North America without any setup. If your masjid follows a slightly different convention, you can switch the method in settings and the whole timetable updates.

Major masjids and the Muslim community in Boston

The anchor of the community is the Islamic Society of Boston Cultural Center (ISBCC) in Roxbury. It opened in 2009, runs to about 70,000 square feet, and is the largest mosque in New England, drawing well over a thousand worshippers to Friday prayer. It grew out of the Islamic Society of Boston, which Muslim students from Harvard, MIT, BU, Northeastern, Tufts, and other campuses founded in 1981.

Across the river sits the Islamic Society of Boston (ISB) at 204 Prospect Street in Cambridge, the city's main masjid, opened in 1995 and busy with students and families through the week. In Dorchester, Masjid Al-Quran on Intervale Street is one of the oldest Muslim institutions in the city. Yusuf Mosque serves the Brighton and Allston side of town, and the Islamic Center of New England in Quincy covers the South Shore. Jumu'ah at the larger venues often runs in two shifts to fit everyone in, so check your masjid's khutbah start time before you head out.

Qibla direction from Boston

From Boston, the Qibla bearing to the Kaaba in Mecca is about 60 degrees from true north, which points roughly east-northeast. The Kaaba is around 10,002 km away. Stand facing the Qibla downtown and you are looking out past the harbor and across the North Atlantic toward Europe and, beyond it, the Arabian Peninsula. FivePrayer's built-in compass reads magnetic north and corrects for local declination, so the arrow lands on true 60 degrees.

Practical tips for praying in Boston

Winter days are short. Around the December solstice the sun sets close to 4:15 PM, which bunches Dhuhr, Asr, and Maghrib into the workday. Use FivePrayer's calendar export to drop short prayer breaks into your schedule so Asr does not slip past while you are in a meeting.

Summer twilight runs late. In late June, Fajr can come before 3:20 AM and Isha lands close to 10:30 PM, since the sky never fully darkens at this latitude. The ISNA angle keeps both within humane bounds, but it still makes for a tight night. Plan your sleep around it the way the local masjids do.

Prayer spaces around the city: Logan Airport has multi-faith prayer rooms in several terminals. Most large campuses, including Harvard, MIT, BU, and Northeastern, keep a Muslim prayer room or musalla open to visitors, and the bigger malls and the Prudential Center have quiet spaces you can use at a pinch. For a full congregation, the ISBCC in Roxbury and the ISB in Cambridge both hold daily jamaat for all five prayers.
