Bulgaria is on Eastern European Time (GMT/UTC plus two hours), except during daylight saving time, when clocks are put forward by one hour between the last Sunday in March and the last Sunday in October. There are no time-zone changes within the country.

If it’s noon in Sofia, it’s 2am in Los Angeles, 5am in New York, 10am in London, 11am in Paris and 7pm in Sydney, not taking into account daylight saving (where applicable) in these countries. The 24-hour clock is commonly used throughout Bulgaria, and always used for bus and train timetables.
