What UTC+4 means
A clock set to UTC+4 shows UTC plus 4 hours. When it is 12:00 noon UTC, it is 4:00 pm here. Compared with India (UTC+5:30) it is 1 hour 30 minutes behind.
Converting to and from UTC+4
To turn UTC into this time, add 4 hours. To go back to UTC, subtract the same amount. Three examples: 6:00 am UTC is 10:00 am here; 3:00 pm UTC is 7:00 pm here; 9:00 am here is 5:00 am UTC. The calendar date changes whenever the sum passes midnight.
Where UTC+4 sits on the map
The Earth turns 15 degrees of longitude every hour. The line where the sun-time matches UTC+4 exactly is 60° east. The places that use it are spread much wider than that one line. Of the main cities listed below, Yerevan (44.5° east) is the farthest west and Muscat (58.4° east) the farthest east. By the sun they are about 56 minutes apart, yet their clocks agree.
Who is on UTC+4, and when
12 zone areas in 9 countries and territories keep UTC+4 through the whole year. The towns of 15,000 or more there hold about 31 million people (GeoNames figures). Nobody moves on to or off this offset during the year, so the list below is the same in every season.
