I keep both an electronic and a paper calendar. That’s a bad system, because I sometimes forget to enter an event on one of them and commit myself to existing in two places at the same time. Thus I’m sympathetic to anyone who messes up a schedule — within limits. These signs definitely do NOT fall within those limits.

Whoever wrote this sign didn’t memorize the “Thirty days hath September, April, June, and November” jingle that I learned in elementary school.

Note to self (on both calendars): Avoid this street every September 31st.

This sign, posted in London, has a similar problem:

I thought the longest night of the year was December 21st, the winter solstice, but apparently it’s 29 Septermeber, which has 3 nights tucked into one date. Or perhaps the road closing begins on 29 Septermeber and lasts until Septermeber 31?

Moving from days to weeks:

There may be Only One NYC RESTAURANT WEEK because that week lasts for a very long time.

This advertisement, which I found in a catalog, stumps me:

I can’t make the numbers add up. From 1983 to 2023, I count 40 YEARS. So far, so good. But how does that connect to aptly named 1963 — a date plastered on all the clothing? Maybe the jackets are half as large as they should be (half of the 40-year span of A WINDPROOF, WATERPROOF LEGEND)? Theories welcome, as long as you send them in before the deadline, which is next September (Septermeber) 31st.
