Convert WET to IST Time Zone
Everything you need for WET to IST — the difference, the current times, and how to plan around it.
How do I convert WET to IST?
It takes three quick steps:
- Click the WET field on the left and pick the time you want to convert.
- The matching IST time updates on the right automatically — there’s no button to press.
- Need a different day? Click the date field and the result follows, rolling over if it crosses midnight.
How many hours apart are WET and IST?
IST is 1 hour ahead of WET. In everyday terms, once you know the time on one side you just add 1 hour to get the other — so a call between Lisbon and Dublin is always 1 hour apart.
What time is it in IST right now?
Right now the time in Irish Standard Time (IST) is Monday, June 29, 2026 · 6:53:58 PM. It ticks every second, so you’re always looking at the live IST clock.
What time is it in WET right now?
And in Western European Time (WET), it’s currently Monday, June 29, 2026 · 5:53:58 PM. Compare the two and the 1 hour gap is easy to see.
Planning a meeting across WET and IST?
For example, a 9:00 AM WET meeting takes place at 10:00 AM IST. 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.
How does daylight saving affect WET to IST?
The labels WET and IST are fixed offsets, so the result on this page is always exact. Both regions move their clocks for daylight saving on roughly the same weekends, so the 1 hour gap usually holds steady right through the year.
Why can you trust this WET to IST converter?
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 WET to IST stays accurate for today and for any past or future date you type in.

Frequently asked questions
How many hours ahead of WET is IST?
IST is 1 hour ahead of WET — a fixed 1 hour difference, since both are fixed-offset labels.
What time is it in IST when it's 12:00 PM WET?
When it's 12:00 PM (noon) WET, it's 1:00 PM IST.
Do WET or IST use daylight saving time?
Western European Time (WET) observes daylight saving, alternating with WEST; Irish Standard Time (IST) observes daylight saving, alternating with GMT.
Why might the real-world WET–IST difference change during the year?
The labels WET and IST are fixed offsets, so this converter is always exact. But Western European Time's region switches between standard and summer time, so for part of the year you may actually want WEST to IST. Always check which label a region is currently using before you schedule.
