How is time zone calculated?
To find the time zone in hours of a particular location, you can take the longitude — in degrees — and divide it by 15. So, for example, 75° E would be 75/15 which equals 5. That translates to the time zone being 5 hours ahead of UTC or GMT time, which can also be labeled as UTC+5.
