Every month of 1981 as a printable table, with public holidays, ISO week numbers and the year's eclipses, moon phases and meteor showers.
1981 has 365 days, starts on a Thursday, is not a leap year, and runs to 53 ISO weeks. It runs from Thursday 1 January 1981 to Thursday 31 December 1981. There are 9 United States federal holidays in 1981, one of which falls at a weekend and is kept on a different day. Worth knowing: 1981 is a 53-week year under ISO 8601, which is the case that breaks payroll and reporting systems written for 52.

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 1981 has 53 weeks and why 1 January is not always
in week 1.

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 1981.

1981 is not a leap year, so February has 28 days. It is also a 53-week year under ISO 8601, which happens roughly every five to six years and regularly breaks payroll and reporting systems that assume 52.
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 1981 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.
