Every month of 2021 as a printable table, with public holidays, ISO week numbers and the year's eclipses, moon phases and meteor showers.
2021 has 365 days, starts on a Friday, is not a leap year, and runs to 52 ISO weeks. It runs from Friday 1 January 2021 to Friday 31 December 2021. There are 11 United States federal holidays in 2021, three of which fall at a weekend and are kept on a different day. Worth knowing: 1 January 2021 falls in week 53 of 2020, not in week 1 of 2021.

Wk ISO 8601 week number
Weeks start on Monday so that the week number in the left gutter applies to the
whole row. ISO 8601 defines week 1 as the week containing the first Thursday of
the year, which is why 2021 has 52 weeks and why 1 January is not always
in week 1.
Public holidays in 2021

Meteor showers
Peak nights drift by about a day between years, because the Earth meets each
stream at a fixed point in its orbit rather than on a fixed date. What
changes the view far more is the Moon, so we compute how much of it is lit
on the peak night of 2021.

2021 is not a leap year, so February has 28 days.
Years you can reuse this calendar for
These years start on the same weekday and have the same February, so the grid
above is identical. A 2021 wall calendar hangs again, unchanged, in any of them.
Public holidays computed from statute, cross-checked against
Nager.Date for every year it covers. Astronomical
events computed with astronomy-engine. Week numbers follow ISO 8601. Times are UTC.
