Family Day is the name of a public holiday in South Africa, in the Canadian provinces of Alberta, British Columbia, Manitoba, and Ontario, in the American states of Arizona and Nevada, in Vanuatu, in Vietnam and (as "Family & Community Day") in the Australian Capital Territory.

Family & Community Day was celebrated on the first Tuesday of November in 2007, 2008 and 2009, coinciding with the Melbourne Cup. This public holiday was declared in 2007 under section 3(1)(b) of the Holidays Act 1953 (ACT). It was announced in 2008 that it would continue on Melbourne Cup Day in 2008 and 2009. Mr. Andrew Barr, the ACT Minister for Industrial Relations stated the purpose of the new public holiday was:

The Melbourne Cup is Australia's major Thoroughbred horse race. Marketed as "the race that stops a nation", it is a 3,200 metre race for three-year-olds and over. It is the richest "two-mile" handicap in the world, and one of the richest turf races. Conducted by the Victoria Racing Club on the Flemington Racecourse in Melbourne, the event starts at 3pm (daylight saving time) the first Tuesday in November.

The race has been held since 1861 (see list of Melbourne Cup winners) and was originally held over two miles (about 3,218 metres) but following preparation for Australia's adoption of the metric system in the 1970s, the current race distance of 3,200 metres was established in 1972. This reduced the distance by 18.688 metres (61.31 ft), and Rain Lover's 1968 race record of 3min.19.1sec was accordingly adjusted to 3min.17.9sec. The present record holder is the 1990 winner Kingston Rule with a time of 3min 16.3sec.
