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 1975 has 52 weeks and why 1 January is not always
in week 1.
Public holidays in 1975
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 1975.

1975 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 1975 wall calendar hangs again, unchanged, in any of them.
Public holidays computed from statute, cross-checked against
