Zulu time

What Zulu time is

Zulu time is UTC. The letter Z stands for the zero offset from UTC, and "Zulu" is how it is spoken. Aviation, maritime, military and weather work use it so everyone shares one clock: a forecast issued at 1430Z means the same moment worldwide. Times are written as four digits on a 24-hour clock with no colon, for example 0930Z.

The lettered zones are fixed whole-hour offsets and do not follow daylight saving. Real places move between letters over the year, so use the time zone converter when you need the exact local time of a city.
