Time ZonesWhat UTC+9 means
A clock set to UTC+9 shows UTC plus 9 hours. When it is 12:00 noon UTC, it is 9:00 pm here. Compared with India (UTC+5:30) it is 3 hours 30 minutes ahead.
Converting to and from UTC+9
To turn UTC into this time, add 9 hours. To go back to UTC, subtract the same amount. Three examples: 6:00 am UTC is 3:00 pm here; 3:00 pm UTC is 12:00 am here on the next day; 9:00 am here is 12:00 am UTC. The calendar date changes whenever the sum passes midnight.
Where UTC+9 sits on the map
The Earth turns 15 degrees of longitude every hour. The line where the sun-time matches UTC+9 exactly is 135° east. The places that use it are spread much wider than that one line. Of the main cities listed below, Chita (113.5° east) is the farthest west and Jayapura (140.7° east) the farthest east. By the sun they are about 1 hour 49 minutes apart, yet their clocks agree.
