HST to GST Converter

It takes three quick steps:

1. Click the HST 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 14 hours ahead of HST. In everyday terms, once you know the time on one side you just add 14 hours to get the other — so a call between Honolulu and Dubai is always 14 hours apart.

Right now the time in Gulf Standard Time (GST) is Monday, June 29, 2026 · 9:53:57 PM. It ticks every second, so you’re always looking at the live GST clock.

And in Hawaii Standard Time (HST), it’s currently Monday, June 29, 2026 · 7:53:57 AM. Compare the two and the 14 hours gap is easy to see.

For example, a 9:00 AM HST meeting takes place at 11:00 PM 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 HST 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.

Every conversion here is calculated from the IANA time zone database — the same source your phone, computer, and browser rely on. Plenty of tools hard-code a single offset, which quietly goes wrong whenever a region changes its rules or flips for daylight saving. We follow the real rules instead, so HST to GST stays accurate for today and for any past or future date you type in.
