What “time in London” means in everyday use
Most people arrive here for one reason: they need the current time in London, right now. The live clock above gives you that instantly.
When you plan ahead, the important detail is that London switches between GMT in winter and BST in summer. That one-hour shift is the most common reason people miss meetings or show up early.
A simple habit that prevents mistakes
When you share a time, write the date and say London. If the timing is important, add GMT or BST so nobody has to guess.
Compare and plan in seconds
If you need more than the current time, use the on-site tools below:
- London time zone — what Europe/London means and why the date matters.
- BST vs GMT — the two labels explained in plain English.
- Daylight saving — what changes, what stays the same, and where mistakes happen.
- World clock — compare London to 20 major cities.
- Meeting planner — map 09:00–17:00 London into 20 cities.
When to double-check
Be extra careful when you are scheduling far ahead, travelling across time zones, or planning around seasonal clock changes.
How to write London times so nobody misreads them
A clear message avoids follow-up questions. A safe format looks like this: Tuesday 14 May, 15:00 (London). If the timing is critical, write 15:00 BST or 15:00 GMT.
That’s enough information for someone else to convert correctly without guessing.
Why conversions go wrong
Most conversion mistakes are not complicated. They happen when people assume London is always on GMT, or when a time is shared without a date.
If you only remember one rule, remember this: date + time + location belongs together.
