Converting CST to PST

Converting time from CST (Chicago, US Central) to PST (Los Angeles, US West) means adjusting for the offset between the two zones — and that offset can shift by an hour twice a year because Chicago and Los Angeles may observe Daylight Saving Time on different schedules. The converter below uses the IANA time-zone database (America/Chicago ↔ America/Los_Angeles), which carries the full DST history and ruleset. Type a time in either side, pick the date, and the matching local time on the other side updates with the correct offset for that exact day. Need to compare more than these two zones? Open the full Time Zone Converter to add up to 6 zones at once, or use the Unix Timestamp Converter for epoch-to-date arithmetic across zones.
