Understanding the +1h Gap: WET vs London
WET runs on Western European Time (WET) at UTC+00:00. London runs on British Summer Time (BST) at UTC+01:00, also currently on daylight saving time. That puts WET 1 hour ahead of London — a difference of +1h at the current offsets.
In practice, when it is 9:00 AM in WET it is 10:00 AM in London. Midnight in WET is 1:00 AM in London.London observes daylight saving time while WET does not, so the gap narrows or widens by an hour part of the year.

Why people convert WET to London time
- Scheduling a call from WET to London: a 10:00 AM start in WET lands at 11:00 AM in London, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both WET and London are inside the 9-to-5 working day between 9:00 AM and 4:00 PM WET time (10:00 AM–5:00 PM BST). That is roughly 7 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in WET is 9:00 PM in London makes it easy to avoid calling at 3 AM.

About WET (Western European Time)

The United Kingdom uses GMT during winter months and switches to British Summer Time (BST, UTC+01:00) from late March to late October. Several West African nations use GMT year-round. GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.
