FAQ
Reader questions
Does Chicago switch between two time offsets each year?
Yes, Chicago observes Daylight Saving Time, moving from UTC−6 in standard time to UTC−5 in summer months, then back again in the fall.
What happens if I schedule a meeting at 1:30 AM on the day clocks spring forward?
The hour from 2:00 AM to 3:00 AM does not exist locally, so you should avoid early morning slots around the transition to prevent confusion.
Will my calendar invite show the correct time when I invite someone from Los Angeles?
Yes, modern calendar tools automatically convert Central Time to Pacific Time for attendees, but it is still wise to double-check the displayed local time before confirming.
Why does Indiana sometimes create confusion around Central Time usage?
Parts of Indiana historically did not observe Daylight Saving Time, and some counties still differ, so it is important to verify local rules when coordinating meetings across the state line.
