"Examples of how to convert from UTC to your local time Let’s say you live in Houston, Texas, which is in Central Standard Time (U.S.). To convert 18 UTC into your local time, subtract 6 hours, to get 12 CST. During daylight saving (summer) time, you would only subtract 5 hours, so 18 UTC would convert to 13 CDT. Or, let’s say you’re in Paris, France, which is in Central European Time. To convert 18 UTC into your local time, add 1 hour, to get 19 CET. In summer, add 2 hours to get 20 CEST. When converting zone time to or from UTC, dates must be properly taken into account. For example, 10 March at 02 UTC is the same as 9 March at 21 EST (U.S.). The table can also be used to determine the difference between the time observed in any two zones. For example, the table shows that Eastern Standard Time is three hours ahead of Pacific Standard Time (U.S.). Bottom line: The Earth has 24 time zones, but when astronomers mention a time, it’s often Coordinated Universal Time, or UTC. This article explains how to translate UTC to your local time zone."
