Presentation Transcript

What is it?

- a.ka. the military time.
- schedules for trains, buses, T.V., radio shows, and other official events use the 24-hour clock
- also differentiates between the a.m. the p.m—don’t need it when you use the 24-Uhr

In German…

- The hour and minutes are separated by a period, not a colon.
- z.B. 13.00 = 1 PM

- When writing the official time, state the hour, then the minutes past the hour never use “nach”, “vor”, or “halb” or “Viertel”
- z.B
- 13.20 = Es ist 13 Uhr 20.
- 18.50 = Es ist 18 Uhr 50.

- z.B

The conversions…

- When using the 24-hour clock, you count from 1 to 24 (the first hour of the day is 1 Uhr, the 17th hour is 17 Uhr)
- Add the number of the hour to 12 to get the military time.
- 1 = 13 7 = 19
- 2 = 14 8 = 20
- 3 = 15 9 = 21
- 4 = 16 10 = 22
- 5 = 17 11 = 23
- 6 = 18 12 = 0/24

To convert back to standard time…

- Subtract 12
- z.B. Es ist 19 Uhr.
--12

=7:00

Therefore, 23.00 = 11 pm.

If it were 11 am, it would be written as 11.00

Es ist 9 Uhr using the 24 Uhr would be a.m., but 9 Uhr at night would have to be 21 Uhr.

More examples…

To say 1:30 p.m. using the 24 Uhr it would be….

13.30 (Es ist 13 Uhr dreißig.)

To say 5:45 p.m. using the 24 Uhr, it would be …

17.45 (Es ist 17 Uhr fünfundvierzig)
