As discussed previously, while we avoid it whenever possible, this year (5784 / 2024) most Ashkenazim will read the actual Haftarah for Kedoshim: Yechezkel Ch. 22, "Inform the bloody city of all its abominations!"
The answer there said the last time it was read was 5757 (1997); after this year, what's the next time it will be read? (Better yet, where's a good place to look up stuff like this?)
