Wikipedia:Today's featured article oddities

The first "Today's Featured Article" section on the main page was on February 22, 2004 ( Wolfgang Amadeus Mozart, since you ask).

The selection did not change at 00:00 (UTC) as it now does, and sometimes articles would appear for more or less than 24 hours.

The system of using daily templates, prepared in advance and automatically transcluded onto the main page, began on August 7, 2004. Since then, things have been a little more regular.

The general rules are that only featured articles appear in the TFA slot, only one FA appears per calendar day, each FA appears for 24 hours, with only one picture, and no FA can appear more than once as TFA.
