Prayer times in Ottawa

Daily Ottawa results and a printable month

To check one day, set Local date or keep Today at this location, then choose Calculate times. The calculator reads the date as an Ottawa calendar date on the Eastern clock, not the date on your phone or laptop. A visitor checking from another time zone still sees the Ottawa day. You can choose any date from 1 January 2020 to 31 December 2035.

The result has six rows: Fajr, Sunrise, Dhuhr, Asr, Maghrib and Isha. Sunrise is a solar marker shown for reference. It is not one of the five prayers.

Times shift a lot across the year. With the default settings at the city centre, on 15 January 2026 Fajr starts at 06:23, Maghrib at 16:46 and Isha at 18:02. On 21 June 2026, Fajr is at 03:36, Maghrib at 20:55 and Isha at 22:33. Maghrib is calculated from sunset, so it follows the length of the day. Fajr and Isha also depend on the twilight setting explained in the next section. Because of that range, this page calculates the date you select instead of quoting one fixed Fajr, Maghrib or Isha time for Ottawa.

Daily times for each prayer and the monthly view all come from this one calculator. Calculation details lists the engine, angles, rules, rounding, offsets and time-zone data behind the numbers. The date and point appear in the main controls.

If you plan to pray in congregation, compare these start times with the mosque's own schedule, as explained in reading Ottawa Adhan and Iqamah columns.

Compare 13° and 15° twilight, then choose Asr

Two settings act on different rows. The twilight angle moves Fajr and Isha. The Asr school moves only Asr. Changing one at a time shows how much each setting moves the result for your chosen date.

Twilight angle: Fajr and Isha

In the angle-based profiles compared here, Fajr begins when the sun, still below the horizon before sunrise, reaches the profile's angle. Isha begins when the sun has sunk to its angle after sunset. Some other profiles work differently, as Calculation methods describes. A 15° angle is deeper than 13°, so the sun crosses it earlier before sunrise and later after sunset. A 15° profile therefore gives an earlier Fajr and a later Isha.

The page starts on FCNA Canada, which uses 13° for both Fajr and Isha. This follows the Fiqh Council of North America's recommendation from its 2017 meeting, published in 2021. It suggested 13°/13° for Canada and 15°/15° for the USA, and it called both approximations. A later FCNA article published on 18 September 2024 discusses the limits of fixed angles and treats 15° as an approximation. It also points to seasonal and local observation and to following trusted local institutions. Neither text says which method a particular Ottawa mosque uses. Treat the default as a declared starting point, which you can change under Calculation profile.

Ottawa centre, 21 June 2026, Angle-based rule, no manual adjustments

Sunrise (05:14), Dhuhr (13:06) and Maghrib (20:55) are the same in all three. On this date, the 15° profile makes Fajr 21 minutes earlier and Isha 21 minutes later. The gap changes through the year, so it is not a fixed correction.

Asr: Standard or Hanafi

Asr is measured by shadows. Even at solar noon, an upright object casts some shadow, called the noon shadow. Under Standard, Asr begins when the shadow equals the object's length plus the noon shadow. Under Hanafi, Asr begins when the shadow equals twice the object's length plus the noon shadow. You change this under Asr calculation, and it affects no other row. On 21 June 2026, switching to Hanafi moves Asr from 17:15 to 18:29.

The shadow demonstration in this section starts with a 1-metre stick and a 0.25-metre noon shadow. Standard then needs a total shadow of 1.25 metres and Hanafi needs 2.25 metres. If you move Illustrative noon shadow (metres), both totals change, because the noon shadow is part of each rule.

Adjustments, rounding and the twilight rule

All six manual adjustments start at 0. The profile still adds one minute to Dhuhr, and all times are rounded to the nearest minute. Twilight rule starts on the Angle-based option. Every Fajr and Isha in this section's examples is an ordinary angle crossing. The high-latitude guide explains the other rule options. Use Load this example on any sample to apply its date and settings to the calculator.

Read Ottawa mosque Adhan and Iqamah correctly

The two Ottawa timetables compared below each pair a start time with a congregation time. The first, labelled Adhan or Athan, is the institution's own start time. The second, labelled Iqamah or Jamaah, is when the congregation stands to pray, and each mosque sets it prayer by prayer. This calculator produces only start times. The diagram in this section uses a hypothetical 13:00 start and 13:20 congregation to show the gap. Those values are an illustration, not an Ottawa measurement.

Example: Masjid ar-Rahmah, observed 4 November 2026

Masjid ar-Rahmah's prayer timetable labels Adhan and Iqamah separately. The page presents it as the current day's times, but the table does not print a calendar date. The figures below are what it displayed when checked on 4 November 2026, next to this calculator's default for the same date. They are a dated observation, not an archived copy.

4 November 2026: our default start (Ottawa centre, FCNA Canada 13°/13°) and ar-Rahmah's displayed times

The mosque's start times are 11 minutes earlier for Fajr and 11 minutes later for Isha than the 13° default. The distance to its Iqamah varies by prayer. Fajr Iqamah came 30 minutes after its Adhan and Isha Iqamah 81 minutes after. On the same day, its Maghrib Adhan was 16:47 and its Maghrib Iqamah 16:52, only five minutes apart. We could not confirm the mosque's full method or exact reference point. Its numbers are not a setting to copy into the calculator. To attend, check its timetable on the day.

A dated historical example: Markaz At-Tawheed, January 2026

The January 2026 calendar from Markaz At-Tawheed lists Athan and Jamaah times. Its row for 15 January 2026 gives Fajr Athan at 06:29 and Isha Athan at 18:14. This calculator's default for that date gives 06:23 and 18:02. Shuruq (07:39) and Dhuhr Athan (12:13) match our Sunrise and Dhuhr. Asr (14:28) and Maghrib (16:47) are each one minute later than ours. The Jamaah times are set separately, for example 06:40 for Fajr, 16:52 for Maghrib and 19:30 for Isha. This old calendar is useful only for comparison. It does not show the centre's method, and it is not a guide to its current times.

Fridays and clock changes

The Ottawa South Muslim Community Centre prayer times page lists the Friday khutbah time and the Jumuah Iqamah separately, so read both before you set out. Check that page itself for the current schedule. Congregation times can also change after a daylight-saving change. Assalam Mosque posted a notice that it had updated its times after a clock change, with its own Iqamah instructions. Such notices may not give an effective date, so confirm the current instructions with the mosque around the March and November changes. Why prayer times differ covers the wider reasons that sources disagree.

Use the Ottawa point and Eastern clock

The calculator's Ottawa preset is the city centre at 45.4215° N, 75.6972° W, on the America/Toronto time zone. That name identifies a clock rule, not a fixed offset. The calculator applies the right offset for whatever date you choose.

Ontario's Time Act (consolidation current to 30 October 2026) sets standard time at UTC−5 for the part of the province east of 90° W, which includes Ottawa. Daylight saving time runs one hour ahead from the second Sunday in March to the first Sunday in November. Amendments for permanent time are marked as not yet in force. These are the nearest changes the calculator applies:

Recent and upcoming Ottawa clock changes

Do not add or subtract an hour yourself. The calculator already applies the change, so doing it yourself would count it twice.

Somewhere other than the centre

Another Ottawa neighbourhood, a particular mosque, or a place across the river in Gatineau each has its own coordinates, so calculate from that point. Use Use my location or Enter coordinates instead to set the exact point. Device and manual points clear the time zone. Select or confirm one under Timezone for this location, because the calculator does not guess it. Choosing another city in Search city presets moves the calculator to that city's point and zone. This article and its examples still describe Ottawa centre. Montreal prayer times has its own page.

Use Ottawa centre again restores the preset point and zone and keeps your date and settings. Reset returns this page's defaults and Today and clears any Ramadan range.

Plan a local Ramadan range and return to Qibla

The page does not fix any Ramadan dates in advance. Use the start your community announces:

1. In the Ramadan timetable, enter First fasting day. This is the Gregorian date of the first daytime fast, not the evening before.
2. Choose Length of Ramadan: 29 or 30 days.
3. Select Show timetable. You get Fajr and Maghrib for each day of the range, using the current point and settings.

Fajr appears as calculated, with no imsak buffer added automatically. Print timetable opens your browser's print dialogue. Copy timetable link copies a URL that holds the range and settings, not the table cells. The link saves your choices as they were when you copied it. A link made from a manual or device point also includes its coordinates and time zone. The Islamic calendar helps with Hijri dates around the month.

Qibla from the same point

Find Qibla uses whatever point the calculator holds at that moment, so a neighbourhood or mosque you entered carries straight over. The Ottawa Qibla guide uses the Ottawa city centre as its reference point. For other cities and tools, start from prayer times.
