Not really its kinda simple tbh rigth at midnigth its a new day that means if if you were born 23:59:59 a clock you be born in the date of lets say jan. the 1. BUT if you were born 00:00:00 you would be borned in a new day jan. the 2.
the day changes right at midnigth 00:00 a clock (kinda simple "math") so no that don't gives you 2 dates :) hope this helped you out.
sorry for that, but thanks for pointing it out, the 24 hour format is just instead of using am/pm it goes on into it hit 24 or 00 so after 12 midday it goes like:
1:00pm = 13:00
2:00pm = 14:00
and so on into 23:00 witch is 11:00pm and then i goes back to 00:00 at midnight. hope this helped? :)
i must say i have no clue, but i don't know how that is where you live but here in Denmark where i live it is like that i posted before, at exactly 00:00:00 (midnight) the days changes. so why you mother got to choose between 2 day is for me a clue :)
