"Zulu" time, more commonly known as "GMT" (Greenwich Mean Time) before 1972, is a time at the Zero Meridian. Currently, it's referred to as Coordinated Universal Time or Universal Time Coordinated (UTC). It is a coordinated time scale, maintained by the Bureau International des Poids et Mesures (BIPM).
Since Greenwich is the site of the “zero meridian,” they called GMT “Zero Time” or simply “Z- Time.” In the phonetic alphabet that the flyers of the time used to make themselves understood on their radios, “Z” became “Zebra.” When the alphabet was changed, the call sign became “Zulu.”
If you are on Eastern Daylight Savings Time (EDT), you would use the second column to find your Zulu Time/UTC. For instance, if it's 11 a.m. Eastern Daylight Savings Time in Washington, D.C., it's 1500 hours in Zulu time/UTC.
Zulu comes from the US military, which assigns global time zones with letter codes. The UTC time zone carries the letter Z, which in the phonetic alphabet is expressed as “Zulu.” And saying Zulu will make you sound more like a fighter pilot. Simple as that.
Also referred to as BZ, Bravo Zulu is a naval signal. meaning “Well Done” usually communicated through. flag hoist or voice radio.
During Eastern Standard Time (EST), we are 5 hours behind Zulu time, and during Eastern Daylight Time (EDT), we are 4 hours behind.
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".
Prior to 1972, this time was called Greenwich Mean Time (GMT) but is now referred to as Coordinated Universal Time or Universal Time Coordinated (UTC). It is a coordinated time scale, maintained by the Bureau International des Poids et Mesures (BIPM). It is also known as "Z time" or "Zulu Time".
5:00 PM (17:00) Zulu = 10:00 AM (10:00) Pacific Daylight. 5:30 PM (17:30) Zulu = 10:30 AM (10:30) Pacific Daylight. 6:00 PM (18:00) Zulu =
Since the NATO phonetic alphabet word for Z is "Zulu", UTC is sometimes known as "Zulu time". This is especially true in aviation, where "Zulu" is the universal standard. This ensures that all pilots, regardless of location, are using the same 24-hour clock, thus avoiding confusion when flying between time zones.
Why Do Pilots Use “Zulu Time”? Pilots use Zulu time to avoid confusion arising from differences in the local time. To avoid this confusion, everyone in aviation agrees to use a single 'standard' time as a reference point. This is what “Zulu time” is in the simplest possible terms.
Answer: The aviation world uses Zulu time, which is derived from the Prime Meridian running through Greenwich, England. Instead of having to convert to local time or local time adjusted for daylight saving time, pilots use Zulu time—adjusting to local time after they land.
Zulu time is the military name for UTC and is used primarily in aviation, at sea, and in the army. Its time is fixed at prime meridian: 0°(zero degrees) longitude; this position is the reason for its other names Z-Time and Zero Time.
For example, if it's 2 p.m. where you are, add 12 hours to the time to get a military time of 1400. Adjust for the time difference where you are, versus GMT. So, if you live in the Eastern Daylight Time zone, add four hours (because the eastern U.S. is four hours behind GMT). This makes your Zulu Time 1800Z.
The Australian government allows writing the time using either the 24-hour clock (11:27), which is commonplace in technical fields such as military, aviation, computing, navigation, transportation and the sciences; or the 12-hour clock (11:27 am).
The United Kingdom uses Greenwich Mean Time or Western European Time (UTC) and British Summer Time or Western European Summer Time (UTC+01:00).
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.
When “Z” (Zulu) is tacked on the end of a time, it indicates that that time is UTC, so really the literal Z is part of the time. What is T between date and time? The T is just a literal to separate the date from the time, and the Z means “zero hour offset” also known as “Zulu time” (UTC).
Greenwich Mean Time (GMT) is the time measured on the Earth's zero degree line of longitude, or meridian. This runs from the North Pole to the South Pole, passing through the Old Royal Observatory in the London suburb of Greenwich.
'Ahoy' originated in the seafaring world, where it was used as an interjection to catch the attention of crew members and as a general greeting. It is often used today by participants in playful imitations of pirate speak.
AYE-AYE – a term used to acknowledge receipt of a command or order from a senior. It means “I have heard the order; I understand it; I will carry it out.”
Ahoy is a signal word used to call to a ship or boat. The word stems from the Middle English cry “Hoy!”, a greeting derived from the Dutch “Hoi”. Seafarers used the word 'ahoy' in song well before the word's first recorded use in print.
