## Calendar structure

The year opens on a Wednesday, so 1 January 2031 falls in ISO week 1 together with the first five days of January.<sup>[1](https://www.datetools.com/calendar/2031)</sup> Because 2031 is a common year, February has 28 days, ending on Friday 28 February.<sup>[3](https://www.epochconverter.com/days/2031)</sup> A day-number listing for the year places 14 June 2031, a Saturday, at day 165 of 365, in week 24 and quarter 2.<sup>[4](https://nerdulator.com/14-june-2031)</sup>

The same day-count listing gives the corresponding Islamic date under the tabular reckoning for that sample date as 23 Safar 1453 AH; the tabular scheme differs from the religious calendar, which begins each month on an actual crescent sighting, so dates may shift by a day either way.<sup>[4](https://nerdulator.com/14-june-2031)</sup>

## Eclipses

Two solar eclipses headline the year. An annular solar eclipse falls on Wednesday 21 May 2031, in which the Moon covers the center of the Sun but leaves a ring of the solar disk visible.<sup>[1](https://www.datetools.com/calendar/2031)</sup> A total solar eclipse occurs later in the year, on November 14, 2031.<sup>[2](https://www.timeanddate.com/eclipse/solar/2031-november-14)</sup>

## Anniversaries in 2031

Two long-standing institutions and events mark significant anniversaries in 2031.
