 We seem to be at cross-purposes (in a very minor way): I decided that my changing the slash to a dash between the dates bracketing a night was a mistake, per MOS. Having changed it back, now I see that you changed another one, which I'd missed before … The MOS section on dashes is under earnest discussion at the moment, but WP:DATESNO says “A night may be expressed in terms of the two contiguous dates using a slash (the bombing raids of the night of 30/31 May 1942),” which seems to fit the bill. (Year-straddling periods are treated similarly.) So if you’re still in there tweaking, please change it back; otherwise, unless you have an objection, I’ll pop by later and do it. (Feel free to drop me a line if you’d like another pair of eyes on any revisions you do in the meantime.) Sorry if I led you astray!—
