@AltCode @luz @sverx Indeed and this is fine but sometimes we have to speak to non-Europeans, like Americans.If you are mildly interested in what I wrote but do not fancy reading a dry post about time notation—and honestly, who could blame you —the TL;DR is: • You can remember the order by recalling that 'A' is before 'P' (alphabetically) • Consider 12 the zero hour, so 12AM is midnight followed by 1AM • Avoid using AM and PM for the 12 hours. Just say 12 midnight or 12 midday/noon
