In American representation, today's date (December 3, 2004) is 12/3/4. It's not often that we get four consecutive digits in the date, so we should enjoy it while it lasts. Maybe we should eat pi for dinner, or spend $1234 at the Apple Store, or something else suitable to the occasion. In the 21st century, we'll have the following four-consecutive-digit days to celebrate: 01/2/3 (last year) 1/23/4 (earlier this year) 12/3/4 (today) 3/2/10 4/3/21 5/4/32 1/2/34 (same digits as today) 6/5/43 2/3/45 7/6/54 3/4/56 8/7/65 4/5/67 9/8/76 5/6/78 6/7/89 3/21/0 (see note) Did I miss including any? Note: I consider 3/21/0 in the 21st century to be March 21, 2100, based on the assumption that the 1st century was the year 1 through the year 100. If you prefer to think of centuries as starting on years ending in 00, then you should put that date first in the list (March 21, 2000).
