Est To Zulu Time

All aspects of meteorology are based upon a world-wide 24-hour clock called Zulu time (Z), more commonly called Coordinated Universal Time (UTC). You will notice all weather maps, radar, and satellite images all have their time expressed in 'Z'. The Zulu term stems from military usage while Coordinated Universal Time is the civilian term for this 24-hour clock.

.Adjusted for Daylight Saving Time (178 places). UTC (GMT/Zulu)-time: Monday, May 3, 2021 at 03:10:57. UTC is Coordinated Universal Time, GMT is Greenwich Mean Time. Great Britain/United Kingdom is one hour ahead of UTC during summer. Note: Time differences regularly change as countries observe varying Daylight Saving Time (DST) schedules. The offsets listed are correct until Sunday, May 16. Observes EST – Eastern Standard Time part of the year, but not currently. Currently has same time zone offset as EST (UTC -5) but different time zone name. Eastern Standard Time (EST) is 5 hours behind Coordinated Universal Time (UTC). Current local time in a clear format. The US/Eastern time is now 07:-05-03.

The origin of these time zones began in the mid 1800's in England. In 1852 the Royal Observatory in Greenwich, England began transmitting time telegraphically and just three years later became the standard time in most of Great Britain. Also, charts and maps were made with reference to the observatory as the 'zero' or prime meridian.

The Zulu Time Converter enables you to convert local time to Zulu or GMT Time. Zulu Time to Local Time conversions can also be calculated for dates and time in the future with adjustments for daylight saving time. Once your have obtained your Zulu to Local Time conversion results you can add them to a calendar or send the page via email.

Over the next few decades a number of locations around the world had developed their own meridians as reference points. The Greenwich meridian was the most popular of these in part due to the reputation for reliability and correctness of the Greenwich Observatory's publications of navigational data.

In 1884, a conference in Washington, D.C. settled the matter where it was agreed to establish a single 'prime' meridian (0° longitude), passing through Greenwich. This was for both for longitude and timekeeping. This 0° meridian divides the Eastern from the Western Hemisphere. Today, one can visit the Royal Observatory and straddle this 0° meridian with one foot in each hemisphere.

With the 360° daily rotation of the earth, the sun is moving 15° each hour which leads to the formation of 24 time zones. However, today the individual zone boundaries are no longer straight, nor are they always continuous, as they have been modified for convenience and to satisfy the desires of sovereign nations.

Time zone offsets are identified as -12 UTC through 0 to +12 UTC with the minus values signifying time 'before' or ahead of prime meridian (which is the Western Hemisphere). At the meeting of the -12 and +12 time zones is the International Date Line.

Moving west across the International Date Line one moves from the -12 UTC time zone to the +12 UTC time zone. This means you advance the clock 24 hours; in essence you advance one day on the calendar. Moving east across the International Date Line means subtracting 24 hours from the clock thereby reversing one day on the calendar.

The 24-hour clock (Z-time) begins at midnight (00Z) at this prime meridian. 00Z for the United States begins in the evening local time. Z-time does not change with the change for daylight saving time but the local time will change. For example, 00Z in the Central STANDARD Time is at 6:00 p.m. but 00Z occurs at 7:00 p.m. in Central DAYLIGHT SAVING Time.

The following tables show z-times for each time zone in the United States and U.S. Territories.

What is Zulu Time?

Zulu Time is the time in the Zero Meridian Time Zone, also called the UTC (Universal) time zone, or GMT (Greenwich Mean Time Zone). It is most commonly used in aviation and the military, as a way to sync up operations and reduce confusion when plannign of operations spanning multiple time zones.

Zulu Time gets its name from the military call sign for the letter “Z”, which is Zulu. Each time zone has a letter and number designation. “Z” is the letter designation of the Zulu time zone. It also refers to the number “0”, the number designation for Zulu time (zero meridian time zone).

About Zulu Time and Time Zone Names

How are time zones named? They have many different names depending on who is using the time zone. But first a little background on time zones.

1300 Zulu To Est

There are 25 time zones in the world, each one separated by 15 degrees of longtitude. Each time zone encompasses a swatch of the globe extending from north to south between two longitude bars 15 degrees apart.

Every time zone has a common name, letter, and number designation. The military uses letters to name time zones. “Z” is the military letter designation of Zulu Time Zone.

Zulu time zone is therefore also represented by the number “0”, or GMT + 0 which is why it is called the zero meridian time zone. It’s common name is either zero meridian time, GMT (Greenwich Mean Time) (referring to the city Greenwich in England), or UTC (Universal Time).

Zero Meridian Time

Zero Meridian time is the same as GMT (Greenwich Mean Time). This is the starting point for the universal time zone numbering system. It’s the time zone that is essentially at the 0 hour, because it is the starting point for the other time zones, which are either plus or minus an hour from this time zone.

Each time zone is numbered from -12 through +12. with each number having a corresponding letter designation. If you are smart, you probably have figured out that one letter would have to be left off, since there are 26 letters in the alphabet. You are correct.

Is Zulu Time Used as Civilian Time Anywhere?

Yes. Zulu time is used as civilian time in several countries. Any country falling in this particular time zone, use it everyday. The countries in Zulu Time Zone include London England, Dublin Ireland, some cities in Ghana, Portugal, and all of Antartica.

The civilians in these countries use the 12-hour clock. So, they use Zulu time in 12-hour format. They also refer to their time zone commonly as GMT or Greenwich Mean Time. Only military personnel refer to it as “Zulu Time”.

What is Zulu Military Time?

Zulu Military time is simply military time in the Zulu time zone (GMT, UTC, or zero meridian). It is the time in 24-hour clock format of time in this time zone.
