Let’s start with the basics! When it comes to telling time, nobody does it like us (Londoners), and nowhere is our creativity more evident than when we tell time.

Just like Central European Time (CET) – 1 hour ahead of Coordinated Universal Time (UTC), or Greenwich Mean / Universal Time (GMT). As if saying GMT wasn’t good enough for us, we decided on creating a new time zone just for London. And thus, The Greenwich Mean Time – or GMT as we know it today was born!

Interesting Facts about London Time Zone

In an effort to be more creative with our time telling system, we decided on labeling the hours from 0-11 as “o’clock” and the rest of the numbers up until 12 “p’clock”. As a result, we now have much more entertaining ways of saying certain times:

11 o’clock: one-eleventh (1/11) o’clock (written as eleven past eleven or written as 55 past eleven)

10 o’clock: two tenths (2/10) p’clock (written as ten to/past ten or written as fifty-five to/past eleven)

9 o’clock: three ninths (3/9) o’clock

8 o’clock: four eighths (4/8) p’clock, eight o’clock in the morning, 8 am

It is also important to mention that while we think of these “o'” and “p’s” prefixes as part of the time itself, they are actually not part of it. Therefore you should always write them with lowercase letters. Just like this – 1.45 I London time zone pm.

Furthermore, by following this scheme Londoners have become extremely creative when telling time. For example, at 11 o’clock at night, we say “eleven o’clock” (written as eleven hundred hours).

This way of telling time was first suggested by the former Mayor of London, Ken Livingstone in 2002. He claimed that not only would it make time-telling more exciting but also help children learn the basics of mathematics far easier. Furthermore, he wanted to introduce this new system gradually so as to avoid confusion and panic among Londoners and tourists alike. However, his successor Boris Johnson didn’t find this idea as fun and consequently dropped it off after just a few weeks. As a result we today still use the old GMT+1 hour until 1:00 am on Sundays when we turn our clocks back by one hour.

What’s more, the capital of England is also known for having some of the most confusing public transport systems in the world. Just to give you an example, nearly every form of transportation includes a different time zone to indicate when it will arrive at each destination.


London is 5 hours ahead of Eastern Standard Time in the United States. If it is noon EST, then it is 5 pm London time. This can be confusing for people new to the city or those who are not used to doing business with people in other parts of the world. However, by understanding the London time zone and how it works you can avoid any awkward situations.
