BRT to WAT Converter

It takes three quick steps:

1. Click the BRT field on the left and pick the time you want to convert.
2. The matching WAT time updates on the right automatically — there’s no button to press.
3. Need a different day? Click the date field and the result follows, rolling over if it crosses midnight.

WAT is 4 hours ahead of BRT. In everyday terms, once you know the time on one side you just add 4 hours to get the other — so a call between São Paulo and Lagos is always 4 hours apart.

Right now the time in West Africa Time (WAT) is Monday, June 29, 2026 · 6:53:58 PM. It ticks every second, so you’re always looking at the live WAT clock.

And in Brasília Time (BRT), it’s currently Monday, June 29, 2026 · 2:53:58 PM. Compare the two and the 4 hours gap is easy to see.

For example, a 9:00 AM BRT meeting takes place at 1:00 PM WAT. The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.

The labels BRT and WAT are fixed offsets, so the result on this page is always exact. Neither side changes its clocks for daylight saving, so the difference you see here is the same in summer and winter.

We don’t guess. BRT and WAT times are worked out from the official IANA time zone database, the trusted standard that operating systems use worldwide. Because daylight-saving rules and regional offsets do change over time, we track those updates rather than relying on a fixed number — which is exactly where many converters slip up.
