Pukul berapa? -What time is it? (formal)

Jam berapa? - What time is it? (informal)

Tepat waktu - on time.

Indonesia uses 24-hour time format, so use pukul 20 instead of 8 pm. Because Indonesia is so large there are three time zones: West: Sumatra, Java and surroundings (Waktu Indonesia Barat <WIB>); Central: Bali and surroundings (Waktu Indonesia Tengah<WITA>); and East: Papua and surroundings (Waktu Indonesia Timur <WIT>). Each zone differs from the next by 1 hour. In spoken indonesian, 12 hour format is prefer to use and adding the time indicator after it.

Examples:

6.00 am = 6:00 pagi

11.00 am = 11:00 siang

6.00 pm = 6:00 sore

11.00 pm = 11:00 malam

'"Jam" ('"lit. clock") or "at time", often added before the time (e.g "pukul 6 pagi" means at 6 am) In written Indonesian, the 24-hour format is used.

Minutes

To say minute. first, you say "the hours" then "kurang/lebih" (lit. less/more) then "the minutes". examples:

6.11 = enam lebih sebelas (lit. six more eleven <minutes>)

11.54 = duabelas kurang enam (lit. twelve less six <minutes>)

use only if the minutes not more or less than 15 minutes, see below.

use the word "setengah" to say half-hour

examples:

6.30 = setengah tujuh (lit. half seven)

11.30 = setengah dua belas (lit. half twelve)

2.31 = setengah tiga lebih satu (lit. half three more one <minute>)

4.25 = setengah lima kurang lima (lit. half five less five <minutes>)

6.16 = setengah tujuh kurang empat belas (lit. half seven less fourteen <minutes>)
