No, he is correct. Labor Day and Thanksgiving can still be (2/7 times) 12 weeks 3 days apart. Also, my proposal increases the 'Christmas shopping season' by one day on average, and also makes it the same length every year. Andrew Usher

In this case, I wasn't referring to a change to Thanksgiving itself (a la "Franksgiving"), but a change to the number of weeks between Labor Day and Thanksgiving. In particular, we had: 2001: Labor Day = September 3rd Thanksgiving Day = November 22nd dates in between = 11 weeks, 3 days 2002: Labor Day = September 2nd Thanksgiving Day = November 28th dates in between = 12 weeks, 3 days 2003: Labor Day = September 1st Thanksgiving Day = November 27th dates in between = 12 weeks, 3 days 2004: Labor Day = September 6th Thanksgiving Day = November 25th dates in between = 11 weeks, 3 days So what happened was that up until 2001, college football teams scheduled 11 games in the season, but then in 2002, since there was an extra week between Labor Day and Thanksgiving, some schools has 12 games instead. This resulted in more teams becoming bowl-eligible (since it's evidently easier to win six games when there are twelve chances rather than eleven to win). The bowl schedule expanded in 2003 in order to accommodate the extra teams becoming bowl eligible. Then in 2004, some schools went back to scheduling only 11 games. There were fewer teams that were bowl eligible, and so bowls were cancelled. But other schools continued to play 12 anyway. Nowadays, 12-game seasons have become the norm (with a possible 13th game in those conferences which have conference championships). But there are still fewer bowl games than there were in 2003, resulting in some bowl-eligible teams (mostly 6-6 teams) not finding room in any bowl to play. But had the Usher Thanksgiving Day been implemented, Thanksgiving would have fallen on November 21, 2002, and November 20, 2003, meaning that those 12th games would never have been played. We'd probably still have 11-game seasons nowadays, with fewer bowl-eligible teams, and nearly enough spots for all of the bowl-eligible (6-5 or better) teams. An interesting exercise is to Google the phrase "quirk in the calendar" -- most of the results discuss how the differing number of weeks between certain holidays affects sports, or even business. The Usher calendar reform (as well as most other calendar reforms) seek to eliminate such quirks.

Indexing from 0 is so obviously the Right Way that I can't imagine why anyone would make the other choice. Andrew Usher |
