Time Zone Schedule Calculator

Calculating your time of day in relation to Greenwich Mean Time (GMT) requires making an addition or subtraction to GMT based on your Time Zone, as listed in the table below. For example, if you want to view a program scheduled at 03:00 GMT and you live in Hawaii (listed in the table as "-10"), you would subtract 10 hours, yielding 17:00 (or 5:00 PM) local time the previous day. If you want to view the same program in Beijing (listed as "+8"), you would add 8 hours, yielding 11:00 (or 11:00 AM) on the same day. These are all standard times, not daylight savings or summer times. To adjust for daylight savings time, move the clock forward one hour in the spring and back again in the fall. For example, 19:00 GMT normally is 11:00 in Los Angeles (Pacific Standard Time), but in the summer it is 12:00 (Pacific Daylight Time).
