Here is every hour of the day in BST and the same moment in EST.

The green rows are the hours when both zones are inside 9 AM to 5 PM. The row marked Now is the hour it is in UK time right now.

A team split between UK and ET is at work together for 4 hours a day.

Taking 9 AM to 5 PM on each clock as the working day, both zones are at work from 1:00 PM to 5:00 PM BST (9:00 AM to 1:00 PM EST).

One day on BST clocks, with the same moments read on EST clocks underneath.

A team spread across two time zones has fewer chances to notice someone drifting away. TeamPredict reads public LinkedIn signals to flag resignation risk early, wherever people work.

The gap between BST and EST moves between 4 hours and 5 hours during the year.

The United States and Europe change their clocks on different Sundays, so for a few weeks in spring and a week in autumn the gap is an hour different from the rest of the year.

Each bar is one calendar year, January on the left. Days are coloured by the gap between BST and EST.

These are the clock changes of both zones in 2026 and 2027.

BST stands for UK time and EST for Eastern Time on this page.

UK time is GMT (UTC+0) in winter and BST (UTC+1) in summer, and this page follows London all year. The clock reads GMT right now. The UK moves its clocks forward on the last Sunday in March and back on the last Sunday in October.

Eastern Time is EST (UTC−5) in winter and EDT (UTC−4) in summer. People write EST all year, and this page does too; the clock reads EDT right now. It moves its clocks forward at 2:00 AM on the second Sunday in March and back at 2:00 AM on the first Sunday in November.

These nearby time zone pairs show the time right now too.

The time zone converter reads one moment on up to 12 clocks, the military time converter turns 24-hour times into AM and PM, and the time duration calculator measures the hours between two moments.

Here are four questions about BST to EST, answered.

What is 9 AM BST in EST?
9:00 AM BST is 5:00 AM EST, and 5:00 PM BST is 1:00 PM EST. From Sunday, November 1, 2026 the gap is 5 hours, so 9:00 AM BST is 4:00 AM EST.
What is the time difference between BST and EST?
UK time (BST) is 4 hours ahead of Eastern Time (EST). The gap between BST and EST moves between 4 hours and 5 hours during the year. The United States and Europe change their clocks on different Sundays, so for a few weeks in spring and a week in autumn the gap is an hour different from the rest of the year. After today, it becomes 5 hours on Sunday, November 1, 2026 and then 4 hours on Sunday, March 14, 2027.
Is the UK on BST all year?
No. The UK is on GMT (UTC+0) in winter and BST (UTC+1) in summer, and right now London reads GMT. UK clocks move forward and back on these days. In 2026: Mar 29 and Oct 25. In 2027: Mar 28 and Oct 31. The gap on this page follows London's real clock.
What is a good time for a meeting between BST and EST?
1:00 PM to 5:00 PM BST (9:00 AM to 1:00 PM EST) is 4 hours when both sides are inside 9 AM to 5 PM, so a meeting there starts and ends in everyone's normal day.

Turnover is cheaper to prevent than to calculate.
