Timothy Pratt wrote today in the NY Times of people getting married today:
They are among the thousands of couples expected to declare their vows of everlasting love in Las Vegas on Wednesday, Dec. 12 — the last such triple-date likely to occur in their lifetimes.Either he thinks people are going to start living much longer ("likely" to make it to the next 01/01/01, and old enough to get married now?) or else he's betting on a major calendar reform - say, to the 13-month Pax calendar with its leap week in 71 out of every 400 years. (Or maybe he belongs to The World Thirteen Moon Calendar Change Peace Movement?) .
Or, more likely, he just didn't want to be too downbeat.
