It feels late BUT it is easy to forget that last year’s was on September 7. It was also on September 7th in 2015 & 2009.
September 7 is as late as it can be.
It is always the 1st Monday of September. So, it can fall between September 1 & September 7 — & as my table shows, it has.
Yes, if you study it you can see the pattern BETWEEN leap years. Look at 2000 to 2003. It was going down by a day: 4, 3, 2 & 1. Then came a leap year. That set it back to 6. Then it was 5, 4, 3 … & then another leap year. Got it?
