CAT to GST Converter

It takes three quick steps:

1. Click the CAT field on the left and pick the time you want to convert.
2. The matching GST 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.

GST is 2 hours ahead of CAT. In everyday terms, once you know the time on one side you just add 2 hours to get the other — so a call between Harare and Dubai is always 2 hours apart.

Right now the time in Gulf Standard Time (GST) is Monday, June 29, 2026 · 9:54:00 PM. It ticks every second, so you’re always looking at the live GST clock.

And in Central Africa Time (CAT), it’s currently Monday, June 29, 2026 · 7:54:00 PM. Compare the two and the 2 hours gap is easy to see.

For example, a 9:00 AM CAT meeting takes place at 11:00 AM GST. 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 CAT and GST 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. CAT and GST 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.
