Daylight saving notes
In the United States and Canada, daylight saving time runs from the second Sunday in March to the first Sunday in November. That affects Central Standard Time (CST).

How many hours apart are CST and ICT?
ICT is 13 hours ahead of CST. In everyday terms, once you know the time on one side you just add 13 hours to get the other — so a call between Chicago and Bangkok is always 13 hours apart.
What's the current time in ICT?
Right now the time in Indochina Time (ICT) is Tuesday, June 30, 2026 · 12:53:56 AM. It ticks every second, so you’re always looking at the live ICT clock.
And what time is it in CST?
And in Central Standard Time (CST), it’s currently Monday, June 29, 2026 · 11:53:56 AM. Compare the two and the 13 hours gap is easy to see.
What's the best time for a CST–ICT call?
For example, a 9:00 AM CST meeting takes place at 10:00 PM ICT. 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.
Does daylight saving time change the CST–ICT difference?
The labels CST and ICT are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.
How accurate is this CST to ICT conversion?
We don’t guess. CST and ICT 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.

Frequently asked questions
How many hours ahead of CST is ICT?
ICT is 13 hours ahead of CST — a fixed 13 hours difference, since both are fixed-offset labels.
What time is it in ICT when it's 12:00 PM CST?
When it's 12:00 PM (noon) CST, it's 1:00 AM ICT the next day.
Do CST or ICT use daylight saving time?
Central Standard Time (CST) observes daylight saving, alternating with CDT; Indochina Time (ICT) is a fixed offset with no daylight saving.
Why might the real-world CST–ICT difference change during the year?
The labels CST and ICT are fixed offsets, so this converter is always exact. But Central Standard Time's region switches between standard and summer time, so for part of the year you may actually want CDT to ICT. Always check which label a region is currently using before you schedule.
