  • Public holiday in the selected country
  • Today
  • Saturday and Sunday
  • 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 1973 has 52 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 1973.
Peak Shower Rate/hour Moon lit Viewing
3 January 1973 Quadrantids (debris from Asteroid 2003 EH1) 110 1% Dark sky, near new moon
22 April 1973 Lyrids (debris from Comet Thatcher) 18 76% Bright moon, only the brightest will show
6 May 1973 Eta Aquariids (debris from Halley's Comet) 50 22% Mostly dark
30 July 1973 Southern Delta Aquariids (debris from Comet 96P/Machholz) 25 2% Dark sky, near new moon
