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 1980 has 52 weeks and why 1 January is not always
in week 1.
Public holidays in 1980
The 11 federal holidays in 5 U.S.C. 6103, with the rules that were actually in force in each year. State and local holidays are not included.

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 1980.

1980 is a leap year, so February has 29 days. A year is a leap year when it divides by 4, except century years, which must also divide by 400. That is why 1900 was not a leap year and 2000 was.
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 1980 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
