So, this is embarrassing ... I'm a native English speaker, and someone told me they're "staying in Dallas through April." Does that mean they're leaving Dallas April 1 or April 30? This post addressed the question, but it only got one answer, and I'm trying to figure out if there are multiple interpretations to this. Thanks!

    Since '1 through 10' includes 10, I would assume April 30 is included. But I've always found it a weird phrase.

    This phrase lacks precision, so it doesn't really tell you when he is leaving. I would guess that he would most likely be in Dallas through at least part of April, but not necessarily all the way until the 30th. Dec 10, 2020 at 20:32

I would say up to April 30. The month mentioned is included. Merriam-Webster is an authoritative dictionary of US English, and they give this as one of the meanings of through:

4—used as a function word to indicate a period of time:
such as [...]
c: to and including
Monday through Friday

Through (Merriam-Webster)

Lexico (Oxford Dictionaries) gives the same 'including' meaning:

5 North American
Up to and including (a particular point in an ordered sequence)
they will be in London from March 24 through May 7

Through (Lexico)
