August 2031 Calendar
Print an August 2031 calendar for the last full month of summer. August 2031 starts on a Friday and ends on a Sunday, so its 31 days take 6 week rows with a Sunday start (5 with Monday), and the month has five Fridays, Saturdays and Sundays. There is no US federal holiday in August: federal law (5 U.S.C. 6103) lists none, so all 21 weekdays are working days. The next federal holiday is Labor Day on Monday 1 September, the day after the month ends, so Labor Day weekend starts on Saturday 30 August. GOV.UK has not yet published the UK bank holidays for 2031, so the UK options show no Summer bank holiday for now rather than a guessed date. The full moon and the last quarter fall a day earlier in US time zones than in UTC, and the calendar puts each phase on the right date for the zone you pick. Choose Classic, Bold, our own sunflower-field artwork, or a planner with goals, a to-do list and notes; add moon phases, week numbers and your own events; download a PDF in US Letter, A4 or A3, a PNG or SVG, or a phone or desktop wallpaper.

Everything runs in your browser: nothing you type is uploaded, and your settings autosave only in this browser. Holidays: US federal days are calculated with their observed weekdays and named as on the US Office of Personnel Management schedules (OPM lists years to 2030; 2031 and later follow the same rules in 5 U.S.C. 6103); Inauguration Day follows 5 U.S.C. 6103(c) and is marked as an observance; US daylight saving time follows 15 U.S.C. §260a; UK clock changes are from GOV.UK (its table to 2028, then the rule it states: the last Sunday in March and October); UK bank holidays are the GOV.UK list for 2026–2028 (GOV.UK has not yet published 2029, 2030 or 2031); Jewish holiday dates (including Purim) are from Hebcal; Islamic dates (Ramadan, Eid al-Fitr, Eid al-Adha, Islamic New Year) are the Umm al-Qura calendar’s for 2026–2031, marked “expected” because local dates follow the moon sighting and can be a day later; Lunar New Year dates are from the Hong Kong Observatory tables; Easter is calculated with the Gregorian computus and matches the US Naval Observatory’s method (Oudin) for every year from 1900 to 2200. Moon phases are calculated in your browser and match the US Naval Observatory table within a minute for 2026–2031; solstice and equinox times are the US Naval Observatory’s for 2026–2031. PDF export uses jsPDF and svg2pdf.js (MIT licence); print at 100% (actual size).

| Starts on | Friday |
| Ends on | Sunday |
| Days | 31 |
| Weekdays (Mon–Fri) | 21 |
| Working days (no federal holiday) | 21 |
| Weekend days | 10 |
| ISO week numbers | 31, 32, 33, 34, 35 |

Holidays in August 2031
United States: no federal holiday in August 2031. The calendar leaves the US set empty rather than filling it with unofficial “national days”; Labor Day follows on Monday 1 September.
UK sets: GOV.UK has not yet published bank holidays for 2031. England and Wales, Scotland and Northern Ireland show no Summer bank holiday for 2031 until it does.
None of the Islamic dates the calendar marks (the start of Ramadan, Eid al-Fitr, Eid al-Adha and the Islamic New Year) falls in August 2031: in the Umm al-Qura calendar August 2031 is in the months of Rabi al-Thani and Jumada al-Ula 1453; Eid al-Adha was expected on 2 April, the Islamic New Year on 23 April, and Ramadan is expected to begin on 15 December 2031.
Sources: federal law, 5 U.S.C. 6103 (the US Office of Personnel Management has not yet published its 2031 holiday schedule; holiday names as in the law and on OPM’s schedules), the Umm al-Qura calendar for the Islamic dates, the US Naval Observatory for moon phases, and the GOV.UK bank holidays list.
Six week rows
| Week starts on | Rows | First row | Last row |
|---|---|---|---|
| Sunday | 6 | Sun 27 July – Sat 2 August | Sun 31 August – Sat 6 September |
| Monday | 5 | Mon 28 July – Sun 3 August | Mon 25 – Sun 31 August |
August 2031 starts on a Friday and has 31 days, so with a Sunday start the 31st falls alone in a sixth row. The calendar makes the rows shorter to fit the page; switch “Week starts” to Monday for five taller rows.
Moon phases in August 2031
| UTC | US Eastern | US Pacific | |

Moon phase times are the US Naval Observatory’s, converted to each time zone. The tool calculates the phases in your browser (within a minute of the USNO table) and puts each one on the date it falls in the time zone you choose under “Moon phase dates for”.
The full moon (01:45 UTC on 3 August) and the last quarter (00:23 UTC on 10 August) are on the evenings of 2 and 9 August in US time zones; the new moon is on 17 August in US Pacific (21:32) but the 18th in US Eastern and UTC.

What day does August 2031 start on?
August 2031 starts on a Friday and ends on a Sunday. It has 31 days: 21 weekdays and 10 weekend days, in 6 week rows when the week starts on Sunday and 5 when it starts on Monday.
Are there any federal holidays in August 2031?
No. Federal law (5 U.S.C. 6103) sets no federal holiday in August. The next one is Labor Day, the first Monday in September: Monday 1 September 2031.
How many working days are in August 2031?
21 in the United States, since every weekday is a working day.
When is Labor Day weekend 2031?
Saturday 30 August to Monday 1 September 2031. Labor Day is the first Monday in September under 5 U.S.C. 6103, and in 2031 that is 1 September, so the long weekend starts at the end of August.
When is the August bank holiday 2031 in the UK?
GOV.UK has not published the 2031 bank holidays yet; its list currently ends in December 2028. The calendar shows no UK bank holidays for 2031 rather than guessing, and says so at the foot of the page. Add the Summer bank holiday under Your events once it is announced.
When is the full moon in August 2031?
3 August 2031 at 01:45 UTC, per the US Naval Observatory. In US time it is the evening before: 21:45 on 2 August in US Eastern and 18:45 on 2 August in US Pacific, so a US calendar shows the full moon on the 2nd.
Why does a US calendar show the last quarter moon on 9 August?
The Moon reaches last quarter at 00:23 UTC on 10 August 2031, per the US Naval Observatory. In US Eastern time that is 20:23 on 9 August and in US Pacific 17:23 on 9 August, so US calendars show it on the 9th; pick your zone under “Moon phase dates for”.
Is Ramadan or Eid in August 2031?
No. In the Umm al-Qura calendar August 2031 is in the months of Rabi al-Thani and Jumada al-Ula 1453, so no Ramadan, Eid or Islamic New Year date falls in it. Ramadan is expected to begin on 15 December 2031.
