May 2031 Calendar
Print a May 2031 calendar with the long weekend already on it. May 2031 starts on a Thursday and ends on a Saturday; its 31 days fit in 5 week rows with either week start. Memorial Day, the month’s only US federal holiday, is Monday 26 May: federal law (5 U.S.C. 6103) sets it on the last Monday in May, and the US Office of Personnel Management has not yet published its 2031 schedule. Memorial Day weekend runs from Saturday 24 to Monday 26 May. Mother’s Day is Sunday 11 May: US law sets it on the second Sunday in May, and the calendar works it out from that rule. Cinco de Mayo falls on Monday 5 May, and Shavuot begins at sundown on Tuesday 27 May, the day after Memorial Day. GOV.UK has not yet published the UK bank holidays for 2031, so the UK options show no Early May or Spring bank holiday for now rather than guessed dates. Choose Classic, Bold, our own blossom-branch artwork with a butterfly and daisies, 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).

Holidays and observances in May 2031
| Date | Day | Holiday | Type |
|---|---|---|---|
| May 5 | Monday | Cinco de Mayo | Observance |
| May 11 | Sunday | Mother’s Day | Observance |
| May 26 | Monday | Memorial Day | Federal holiday |
| May 27 | Tuesday | Shavuot begins at sundown | Observance |
| May 29 | Thursday | Shavuot ends | Observance |
UK sets: GOV.UK has not yet published bank holidays for 2031. England and Wales, Scotland and Northern Ireland show no Early May or Spring bank holiday for 2031 until it does; with Observances ticked they show Shavuot.
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 May or June 2031: in the Umm al-Qura calendar Eid al-Adha is expected on 2 April, the Islamic New Year on 23 April and Ramadan 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), 36 U.S.C. §117 (Mother’s Day is the second Sunday in May), Hebcal for Shavuot, the Umm al-Qura calendar for the Islamic dates, the US Naval Observatory for moon phases, and the GOV.UK bank holidays list.
Mother’s Day and Memorial Day weekend
| Date | How it is set | |
|---|---|---|
| Cinco de Mayo | Monday 5 May | Every year on 5 May |
| Mother’s Day | Sunday 11 May | Calculated: second Sunday in May (36 U.S.C. §117) |
| Memorial Day weekend | Saturday 24 – Monday 26 May | Memorial Day is the last Monday in May (federal holiday, 5 U.S.C. 6103) |
| Shavuot | Sundown Tuesday 27 – Thursday 29 May | Hebcal 2031 |
Both US dates follow fixed weekday rules, so the calendar works them out for any year you choose. Memorial Day is always a Monday, so it never moves to an observed day.
Moon phases in May 2031
| UTC | US Eastern | US Pacific | |
|---|---|---|---|
| Full moon | May 7, 03:40 | May 6, 23:40 | May 6, 20:40 |

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 full moon is on 7 May in UTC but on the evening of 6 May in US time (23:40 Eastern, 20:40 Pacific); the other three phases fall on the same date in all three.

What day does May 2031 start on?
May 2031 starts on a Thursday and ends on a Saturday. It has 31 days: 22 weekdays and 9 weekend days, in 5 week rows whether the week starts on Sunday or Monday.
When is Memorial Day 2031?
Monday 26 May 2031. Federal law (5 U.S.C. 6103) makes Memorial Day the last Monday in May, so it is always a Monday and never needs an observed day. Memorial Day weekend runs from Saturday 24 May to Monday 26 May. The US Office of Personnel Management has not yet posted its 2031 list.
When is Mother’s Day 2031?
Sunday 11 May 2031 in the United States. US law (36 U.S.C. §117) says “The second Sunday in May is Mother’s Day”; the calendar calculates the date from that rule. The UK’s Mothering Sunday is earlier, on 23 March 2031, three weeks before Easter.
What holidays are in May 2031?
In the United States, Memorial Day on Monday 26 May is the only federal holiday. The calendar also marks Cinco de Mayo (Monday 5 May), Mother’s Day (Sunday 11 May) and Shavuot (from sundown on Tuesday 27 May to Thursday 29 May) as observances.
When is Shavuot 2031?
Shavuot begins at sundown on Tuesday 27 May 2031 and ends on Thursday 29 May, per Hebcal (Shavuot I on 28 May, Shavuot II on 29 May).
Is Ramadan or Eid in May 2031?
No. In the Umm al-Qura calendar Eid al-Adha 2031 is expected on 2 April and the Islamic New Year on 23 April, and Ramadan is expected to begin on 15 December 2031, so none of them falls in May. May 2031 is in the months of Muharram and Safar 1453.
Are there bank holidays in May 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 them under Your events once they are announced.
How many working days are in May 2031?
22 weekdays, or 21 working days after Memorial Day.
When is the full moon in May 2031?
7 May 2031 at 03:40 UTC, per the US Naval Observatory. In US time it is the evening before: 23:40 on 6 May in US Eastern and 20:40 on 6 May in US Pacific, so a US calendar shows the full moon on the 6th.
