December 2031 Calendar

Print a December 2031 calendar for the holiday season. December 2031 starts on a Monday and ends on a Wednesday, so its 31 days fit in 5 week rows with either week start. Christmas Day is Thursday 25 December, the month’s only US federal holiday under federal law (5 U.S.C. 6103); it is a weekday, and New Year’s Day 2032 is a Thursday too, so no observed day moves into December. Hanukkah begins at sundown on Tuesday 9 December and ends on Wednesday 17 December, and Ramadan is expected to begin on Monday 15 December (Umm al-Qura calendar; local dates follow the moon sighting and can be a day later). The winter solstice is Monday 22 December at 01:55 UTC, which is still the evening of Sunday 21 December in US time zones (8:55 pm Eastern). GOV.UK has not yet published the UK bank holidays for 2031, so the UK options leave Christmas Day and Boxing Day unmarked and say so rather than guess. Choose Classic, Bold, our own snowy night with pine trees, or a planner with goals, a to-do list and notes; add moon phases, week numbers and your own events such as a school concert or a holiday party; 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.

Dates in this table are for US Eastern time; in UTC, the UK and Japan the solstice is on 22 December.

UK sets: GOV.UK has not yet published bank holidays for 2031. England and Wales, Scotland and Northern Ireland show no bank holiday for 2031 until it does; with Observances ticked they show Hanukkah, the start of Ramadan, the solstice, Christmas Eve and New Year’s Eve.

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 Hebcal Jewish calendar for Hanukkah, the Umm al-Qura calendar for the start of Ramadan, the US Naval Observatory for the solstice and moon phases, and the GOV.UK bank holidays list.

New Year’s Day 2032Thursday 1 January

Christmas Day and New Year’s Day both fall on Thursdays, with the eves on the Wednesdays before them. Christmas Eve and New Year’s Eve are observances, not federal holidays, so the calendar marks only Christmas Day in red.

Hanukkah and Ramadan 2031

DateSource
Hanukkah begins at sundownTuesday 9 DecemberHebcal
Ramadan begins (expected)Monday 15 DecemberUmm al-Qura calendar
Hanukkah endsWednesday 17 DecemberHebcal

The start of Ramadan is marked “expected” because local dates follow the moon sighting and can be a day later. Ramadan runs past the end of the month, and the mini January 2032 calendar on the page shows dates only, so Eid al-Fitr (expected 14 January 2032) is not drawn on this page.

Winter solstice 2031

UTC and UK (GMT)Monday 22 December, 01:55
US Eastern (EST)Sunday 21 December, 20:55
US Pacific (PST)Sunday 21 December, 17:55
Japan (JST)Monday 22 December, 10:55

The solstice is on the 22nd in UTC, the UK and Japan, but on the evening of Sunday 21 December in every US time zone. Pick a zone under “Moon phase dates for” and the calendar puts the solstice and the moon phases on the right date for it.

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 last quarter (03:19 UTC on 7 December) and the first quarter (00:00 UTC on 21 December) both fall on the evening before in US time zones; the new moon (14 December) and the full moon (28 December) are on the same date in UTC and US time.
