What day would you say September ends?

[AintNobodyHereButUsChickens]

I had a playlist on and Wake Me Up When September Ends came on, and my 5yr old has asked me to wake him up when September ends. What day would you say that was? 30th Sept or 1st Oct?

the midnight between the two surely

1 October I’d say

31 September obviously. How can it be the end of September in October? 🤔

Midnight 30th Sept.

Just before midnight on the 30th

I'm assuming here he wants to witness the end of September.

Indeed, and how can it be the 31st of September either? A date that doesn’t exist 😆

Def the last hour of Sept 30th.

The stroke of midnight on September 30th

The last day of September is the 30th, the last of something is when it ends, so it ends on 30th September.

1 second past midnight Sept 30th.

Or October 1st

No on 1st October September has ended and October has started.

Or are some people going to try to claim that October starts on 30th September whilst September doesn't end until 1st October???

Well, October starts at 00:00 on the 1st October, so I guess September ends at 23:59:59 on the 30th Sept?

This.

Is this a trick question? 🧐

Or do the two things happen at the exact same moment in time?

As he's five I'd tell him at bedtime that that's the end of September and when he wakes up it will be October.
