March 2031 Calendar
Print a March 2031 calendar with the clock change and the equinox on the right day. March 2031 starts on a Saturday and ends on a Monday, so its 31 days take 6 week rows whether the week starts on Sunday or Monday. There is no US federal holiday in March 2031, so all 21 weekdays are working days; the US Office of Personnel Management has not yet published its 2031 schedule, and federal law (5 U.S.C. 6103) sets none in March. Daylight saving time begins on Sunday 9 March, the second Sunday in March under federal law. Purim begins at sundown on Saturday 8 March, St. Patrick’s Day is Monday 17 March, and the spring equinox is Thursday 20 March at 19:41 UTC, which is the 20th in every US time zone. Easter 2031 is on Sunday 13 April, so Ash Wednesday was 26 February and Good Friday falls in April. In the UK the clocks go forward on Sunday 30 March and Mothering Sunday is 23 March; GOV.UK has not yet published the 2031 bank holidays, so the UK options show none for now rather than guessed dates. Choose Classic, Bold, our own windy-spring artwork with a kite and the first yellow flowers, 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 March 2031
| Date | Day | Holiday | Type |
|---|---|---|---|
| Mar 8 | Saturday | Purim begins at sundown | Observance |
| Mar 9 | Sunday | Daylight saving time begins | Observance |
| Mar 17 | Monday | St. Patrick’s Day | Observance |

UK sets: GOV.UK has not yet published bank holidays for 2031. With Observances ticked they show Purim (8 March), the equinox, Mothering Sunday (23 March) and the clock change (Sunday 30 March).
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), 15 U.S.C. §260a for daylight saving time, Hebcal for Purim and Passover, the US Naval Observatory for the equinox, moon phases and the Easter method, GOV.UK for the UK clock change rule, and the GOV.UK bank holidays list.
Clock changes and the equinox
| Date | Time | |
|---|---|---|
| US daylight saving time begins | Sunday 9 March | 2:00 a.m. local time |
| Spring equinox, UTC | Thursday 20 March | 19:41 |
| Spring equinox, US Eastern | Thursday 20 March | 15:41 |
| Spring equinox, US Pacific | Thursday 20 March | 12:41 |
| UK clocks go forward | Sunday 30 March | 1:00 a.m. |
Easter is calculated with the Gregorian computus; the US Naval Observatory’s published Easter method (Oudin, 1940) gives the same date, Sunday 13 April 2031, so Ash Wednesday was 26 February and Mothering Sunday is 23 March. Moon phase times after 9 March are shown in daylight time in the US zones; the tool converts each time with your device’s time-zone rules.
Moon phases in March 2031
| UTC | US Eastern | US Pacific | |
|---|---|---|---|
| First quarter | Mar 1, 04:02 | Feb 28, 23:02 | Feb 28, 20:02 |
| Full moon | Mar 9, 04:29 | Mar 8, 23:29 | Mar 8, 20:29 |

| New moon | Mar 23, 03:49 | Mar 22, 23:49 | Mar 22, 20:49 |
| First quarter | Mar 31, 00:32 | Mar 30, 20:32 | Mar 30, 17:32 |
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”.
In UTC March 2031 has five phases, with first quarter moons on 1 and 31 March. In US time the first one is still 28 February and the last one 30 March; the full moon is on 8 March in US time (23:29 Eastern) but 9 March in UTC, and the new moon is on the evening of 22 March in the US.

What day does March 2031 start on?
March 2031 starts on a Saturday and ends on a Monday. It has 31 days: 21 weekdays and 10 weekend days, in 6 week rows with either week start, because the 1st is a Saturday and the 31st a Monday.
When does daylight saving time start in 2031?
Sunday 9 March 2031 at 2:00 a.m. local time, when clocks go forward one hour. Federal law (15 U.S.C. §260a) sets the start as the second Sunday in March.
When is the spring equinox in 2031?
Thursday 20 March 2031 at 19:41 UTC, per the US Naval Observatory. That is 15:41 in US Eastern daylight time and 12:41 in US Pacific, so it is on the 20th in all three.
What day is St. Patrick’s Day 2031?
Monday 17 March 2031. It is an observance, not a federal holiday, in the US. In Northern Ireland it is usually a bank holiday, but GOV.UK has not published the 2031 dates yet, so the calendar does not mark one.
Are there federal holidays in March 2031?
No. Federal law (5 U.S.C. 6103) puts Washington’s Birthday in February and Memorial Day in May, with nothing in March, so all 21 weekdays are working days. The US Office of Personnel Management has not yet posted its 2031 list.
When is Purim 2031?
Purim begins at sundown on Saturday 8 March 2031 and is celebrated on Sunday 9 March, per Hebcal; in Jerusalem, Shushan Purim follows on Monday 10 March.
Is Ramadan in March 2031?
No. Ramadan 2031 does not fall in March: in the Umm al-Qura calendar the fast that ends with Eid al-Fitr began on 26 December 2030 and ended with Eid al-Fitr on 24 January 2031, and the next Ramadan is expected to begin on 15 December 2031.
When do the clocks change in the UK in March 2031?
Sunday 30 March 2031 at 1:00 a.m., when the clocks go forward one hour. GOV.UK gives the rule as the last Sunday in March. Mothering Sunday, three weeks before Easter, is 23 March.
When is the full moon in March 2031?
9 March 2031 at 04:29 UTC, per the US Naval Observatory. In US Eastern time that is 23:29 on Saturday 8 March, a few hours before the clocks go forward, and 20:29 on 8 March in US Pacific, so US calendars show it on the 8th.
