This is how I tell military time, so let’s say you see it says 15:00pm the trick that I….invented? (No ones taught me this so idk) Was to always subtract by 2.
So 15:00 – 2 would be 13:00, which means its 3:00pm. Now obviously 13:00pm is 1:00pm, but thats not the point. The point is that if someone tells you its 15:00pm u subtract by 2 and u see 13:00pm u just see the 3 so its 3pm.
I’m not good at explaining things as you can see, but I hope you understand what I mean.
