Zulu time is UTC, or Coordinated Universal Time. The letter Z in military time zones is spoken as Zulu, so 1400Z means 1400 UTC.
Why Use Zulu Time
Units and aircraft operating across time zones need one shared clock. Zulu time prevents local time confusion in weather, flight plans, orders, and global communications.
How to Read It
A time written with Z at the end is read as Zulu. For example, 2130Z is twenty one thirty Zulu.
