Presumably by 2400 you mean 24:00 as the time. There is no time 24:00 as a minute after 23:59 would normally be written as 00:00, which would be midnight.
No. After 2300 hours comes 0000. In 24-hour time, the time always means "hours since midnight". 2400 hours would be 0 hours and 0 minutes since midnight, so that time is 0000 hours.

To determine whether 2400 (or 12:00 AM) is today or tomorrow, you need to consider the current time and date. If it is currently before 2400, then 2400 is today; if it is already past 2400, then it refers to the next day, or tomorrow. Always remember that 2400 marks the transition to a new day.
