Hello everyone, I made a quick search on this forum, but couldn't find any answer so I thought I'd ask here. When you write hours, for instance "The train leaves at 3.00 PM", how should you write the "PM" ? Do you capitalize the letters ? Or is it correct to put small letters ? Or do you capitalize the first one and not the second one ? (Pm) Also, should there be dots in between: P.M. ? Or can I just write it the way I like ? Thank you very much for your answers.
