Built for anyone juggling time across the Channel

This CEST to BST converter takes the confusion out of scheduling across Central Europe and the UK. Whether you're booking meetings, organizing travel, or just making sure you're not texting someone in bed, this tool instantly shows you what time it is on the other side.

For example, if you're planning a business call from Spain to Ireland, this converter makes it easy to see that 10:00 AM in Madrid is 9:00 AM in Dublin during summer. No guesswork, no Googling.

Here’s how it works in simple steps

Start by picking your time

At the top, select a date and time in the input fields. You can choose whether you're starting from Central Europe or the UK using the dropdown selector. The tool defaults to CEST (Central Europe), but you can switch to BST (UK) at any time.

Want it to convert automatically? It will

As you enter a time, the tool can automatically calculate the converted time in the other zone. This feature is turned on by default, but if you prefer to hit the button manually, just uncheck “Auto Convert.”

Click to swap or reset whenever you want

Click the "Swap" button to flip the direction, if you were converting from CEST to BST, now it'll go the other way. You can also hit "Reset" to go back to the current time and default settings. It’s all instant.

There’s more under the hood if you want it

Daylight saving aware

The tool automatically checks whether your selected date is in summer or winter and adjusts the UTC offset accordingly. That means it accounts for CEST switching to CET and BST to GMT as needed.

UTC offset display and seconds

You can toggle whether the UTC offset is displayed and whether to include seconds in the time format. Want to see the full time down to the second? Just check the box labeled “Show Seconds.”

Switch between 12-hour and 24-hour clock

Click the “12 Hour” or “24 Hour” button to choose your preferred format. If you’re used to military time or just want AM/PM, it adjusts everything instantly, including the live clocks.

Live time for both zones

Even when you're not converting a specific time, the bottom section always shows the current time in both time zones. You’ll see the real-time difference between Berlin and London as it ticks by.

A quick example from real life

Imagine you're working remotely from Vienna and collaborating daily with a team based in Belfast. You plan a call every morning at 10:00 AM CEST, which is 9:00 AM BST. With this tool, you can double-check that you're aligned, especially when the clocks change in spring and fall. It keeps you synced, no matter the season.

Keep your European calendar running without a hitch

From freelancers and managers to travelers and event planners, this converter takes a lot off your plate. No more second-guessing if the UK is on the same schedule as the EU or whether clocks have changed yet. Plug in a time, get the answer, and move on with your day. It’s simple, clear, and always on time.
