Built for Clear, Instant Time Conversion

This tool converts time between BST (or GMT in the winter) and WIB in seconds. It’s made with flexibility in mind, giving you control over how time is displayed, whether to account for daylight saving, and even includes a swap feature when you want to flip which country is the input.

Why This Is Useful

Indonesia and the United Kingdom are separated by a significant time difference - six or seven hours, depending on the season. If you're scheduling meetings, interviews, or online events across these two countries, making an error on the hour can cause confusion. This converter keeps things accurate, and gives both sides a clear picture of the corresponding time without needing to calculate it yourself.

How to Use It

Step 1: Pick Your Input Time

Choose a date and time from the British or Indonesian time zone, depending on your starting point. The tool starts with British Summer Time selected, but you can switch to WIB using the dropdown.

Step 2: Customize Your Settings

You’ll see checkboxes for:

Auto Convert - Updates results as soon as you adjust the input time.
Daylight Saving Aware - Automatically adjusts for UK summer or winter time.
Show UTC Offset - Reveals the exact UTC difference for clarity.
Show Seconds - Useful for precise tasks like server logs or timed launches.

Step 3: Press “Convert Time” or Use Auto Convert

If auto convert is turned off, just hit the convert button. You’ll get a clear display of the corresponding time in the opposite zone, along with useful extras like the date, UTC offset, time difference, and whether daylight saving is active.

Step 4: Use Quick Tools for Speed

There are four handy buttons in the middle:

Convert - Manually triggers the conversion.
Swap - Flips input and output zones instantly.
Now - Fills in the current time for you.
Reset - Returns everything to default settings and current time.

Features You Might Not Notice Right Away

The converter is packed with thoughtful extras. For example, the current time in both zones is always displayed in real-time, so you don’t need another clock tab open. There’s also a toggle to switch between 12-hour and 24-hour format, whichever you prefer.

If you enter a date that falls in the UK’s winter months, the converter automatically switches from BST to GMT. The tool knows exactly when those daylight saving transitions happen each year.

Practical Example: London to Jakarta

Say you’re scheduling a call between someone in London and someone in Jakarta. You want it at 3 PM in London during July. That would be 9 PM in Jakarta. Rather than checking world clocks or doing mental math, pop 3 PM BST into the converter and get the WIB result instantly—plus confirmation of whether daylight saving is in play, and how big the time gap is.

Keep UK–Indonesia Coordination Effortless

Whether you’re running an international team or planning a video call between family in different corners of the globe, this tool trims the friction out of time conversion. With automatic DST handling, live clocks, and one-click swapping, it's built to give you clarity fast. The next time the UK and Indonesia are on your calendar, let this be the first tab you open.
