September 2033 Calendar
Print a September 2033 calendar for the start of the school year and of autumn. September 2033 starts on a Thursday and ends on a Friday; its 30 days fit in 5 week rows with either week start, and the month has five Thursdays and Fridays. Labor Day, the month’s only US federal holiday, is Monday 5 September 2033, the first Monday in September under federal law (5 U.S.C. 6103), so the long weekend runs from Saturday 3 to Monday 5 September. The US Office of Personnel Management has not yet published its 2033 schedule. The September equinox, the start of autumn in the Northern Hemisphere, is Thursday 22 September at 16:51 UTC (12:51 pm in US Eastern time, 9:51 am in US Pacific), and Rosh Hashanah begins at sundown the next day, Friday 23 September. Yom Kippur and Sukkot follow in October this year. GOV.UK has not yet published the UK bank holidays for 2033, so the UK options say so rather than guess. Choose Classic, Bold, our own apple-orchard 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, 2031, 2032 or 2033); 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 2026–2033, 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 2026–2033; solstice and equinox times are the US Naval Observatory’s for 2026–2033.

|---|---|---|---|
| Sep 5 | Monday | Labor Day | Federal holiday |
| Sep 22 | Thursday | Autumn equinox | Observance |
| Sep 23 | Friday | Rosh Hashanah begins at sundown | Observance |
UK sets: GOV.UK has not yet published bank holidays for 2033. England and Wales, Scotland and Northern Ireland show no bank holiday for 2033 until it does; with Observances ticked they show the equinox and Rosh Hashanah.
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 September 2033: in the Umm al-Qura calendar September 2033 is in the months of Jumada al-Akhirah and Rajab 1455; Eid al-Adha was expected on 11 March, the Islamic New Year on 1 April, and Ramadan is expected to begin on 23 November 2033.
Sources: federal law, 5 U.S.C. 6103 (the US Office of Personnel Management has not yet published its 2033 holiday schedule; holiday names as in the law and on OPM’s schedules), Hebcal for the Jewish holidays, the US Naval Observatory for the equinox and moon phases, the Umm al-Qura calendar for the Islamic dates, and the GOV.UK bank holidays list.
Labor Day weekend 2033
| Date | |
|---|---|
| Saturday | 3 September |
| Sunday | 4 September |
| Labor Day (federal holiday) | Monday 5 September |
Labor Day is always the first Monday in September, so in 2033 the long weekend runs Saturday 3 to Monday 5 September.
Autumn equinox 2033
| Time zone | September equinox |
|---|---|
| UTC | Thursday 22 September, 16:51 |
| US Eastern (EDT) | Thursday 22 September, 12:51 |
| US Pacific (PDT) | Thursday 22 September, 09:51 |
| Hawaii (HST) | Thursday 22 September, 06:51 |
| UK (BST) | Thursday 22 September, 17:51 |
| Japan (JST) | Friday 23 September, 01:51 |
The equinox is on Thursday 22 September in UTC, the US and the UK, and on Friday 23 September in Japan. Pick a zone under “Moon phase dates for” and the calendar puts the equinox and the moon phases on the right date for it.
High Holy Days and Sukkot 2033
| Begins at sundown | Days | |
|---|---|---|
| Rosh Hashanah | Friday 23 September | Saturday 24 – Sunday 25 September |
| Yom Kippur | Sunday 2 October | Monday 3 October |
| Sukkot | Friday 7 October | Saturday 8 – Friday 14 October |
| Shemini Atzeret / Simchat Torah | Friday 14 October | Saturday 15 / Sunday 16 October (outside Israel) |
Dates from Hebcal. Only Rosh Hashanah falls in September this year; the calendar marks the evening each one begins, so Yom Kippur and Sukkot are on the October page. Shemini Atzeret and Simchat Torah are not drawn: add them under Your events if you need them.
Moon phases in September 2033
| UTC | US Eastern | US Pacific | |
|---|---|---|---|
| First quarter | Sep 2, 02:23 | Sep 1, 22:23 | Sep 1, 19:23 |
| Full moon | Sep 9, 02:20 | Sep 8, 22:20 | Sep 8, 19:20 |
| Last quarter | Sep 15, 17:33 | Sep 15, 13:33 | Sep 15, 10:33 |
| New moon | Sep 23, 13:40 | Sep 23, 09:40 | Sep 23, 06:40 |
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 first quarter (02:23 UTC on 2 September) and the full moon (02:20 UTC on 9 September) both fall on the evening before in US time zones, so a US calendar shows them on 1 and 8 September; the last quarter and the new moon are on the same dates everywhere in the table.

What day does September 2033 start on?
September 2033 starts on a Thursday and ends on a Friday. It has 30 days: 22 weekdays and 8 weekend days, in 5 week rows whether the week starts on Sunday or Monday.
When is Labor Day 2033?
Monday 5 September 2033. Labor Day is a US federal holiday on the first Monday in September under federal law (5 U.S.C. 6103), so Saturday 3 to Monday 5 September is a three-day weekend for many. It is always a Monday, so there is never a separate observed day.
When is Rosh Hashanah 2033?
Rosh Hashanah 2033 begins at sundown on Friday 23 September; the first day is Saturday 24 September and the second Sunday 25 September, per Hebcal.
When is the fall equinox 2033?
Thursday 22 September 2033 at 16:51 UTC, per the US Naval Observatory: 12:51 pm in US Eastern time and 9:51 am in US Pacific, so it is on the 22nd across the US and in the UK (5:51 pm). In Japan it is already Friday 23 September (1:51 am). It is the first day of autumn in the Northern Hemisphere.
When is the full moon in September 2033?
9 September 2033 at 02:20 UTC, per the US Naval Observatory. In US time zones that is still the evening of 8 September (22:20 Eastern, 19:20 Pacific), so a US calendar shows it on the 8th. It is the full moon nearest the September equinox: 13 days before it, while the October full moon is 15 days after.
Why does a US calendar show the first quarter on 1 September?
The first quarter is at 02:23 UTC on 2 September 2033, per the US Naval Observatory: that is 22:23 on 1 September in US Eastern time and 19:23 in US Pacific. Pick your zone under “Moon phase dates for” and the calendar puts each phase on the right date.
How many working days are in September 2033?
22 weekdays, or 21 working days after Labor Day.
Are Yom Kippur and Sukkot in September 2033?
No. In 2033 Yom Kippur begins at sundown on Sunday 2 October and Sukkot at sundown on Friday 7 October, per Hebcal, so both are on the October 2033 calendar. September has Rosh Hashanah only.
Is Ramadan or Eid in September 2033?
No. In the Umm al-Qura calendar September 2033 is in the months of Jumada al-Akhirah and Rajab 1455. Eid al-Adha 2033 was expected on 11 March and the Islamic New Year on 1 April, and Ramadan is expected to begin on 23 November 2033.
Are there bank holidays in September 2033 in the UK?
No bank holiday usually falls in September in any UK nation: in GOV.UK’s list from 2019 to 2028 the only one was a one-off, 19 September 2022. GOV.UK has not published the 2033 list yet (its list currently ends in December 2028), so the calendar shows no UK bank holidays for 2033 rather than guessing, and says so at the foot of the page.
