Frequently asked questions
What is CDT to JST time difference?
On paper, CDT is UTC −5 and JST is UTC +9. In practice the two abbreviations are rarely observed at the same time of year — right now Chicago is on CDT and Tokyo is on GMT+9, and the live clock and 24-hour table on this page follow those real wall clocks, which is what you want for scheduling.
Does CDT change for daylight saving?
Yes — CDT is the summer (DST) form of its time zone.
What time is 9am CDT in JST?
9:00 AM CDT ≈ 11:00 PM JST.
