Time ZonesWhat UTC−9 means
A clock set to UTC−9 shows UTC minus 9 hours. When it is 12:00 noon UTC, it is 3:00 am here. Compared with India (UTC+5:30) it is 14 hours 30 minutes behind.
Converting to and from UTC−9
To turn UTC into this time, subtract 9 hours. To go back to UTC, add the same amount. Three examples: 6:00 am UTC is 9:00 pm here on the previous day; 3:00 pm UTC is 6:00 am here; 9:00 am here is 6:00 pm 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° west. The places that use it are spread much wider than that one line. Of the main cities listed below, Anchorage (149.9° west) is the farthest west and Juneau (134.4° west) the farthest east. By the sun they are about 1 hour 2 minutes apart, yet their clocks agree.
Who is on UTC−9, and when
No place with a town of 15,000 people or more keeps UTC−9 through the whole year. 2 more zone areas are on it for only part of the year: for 2 of them it is the standard (winter) time. That is why the number of people on UTC−9 rises and falls with the seasons.
