Scheduling across US time zones becomes easy when you pick a single “source timezone” and convert everything from it.

Below are practical windows that usually work well for calls and meetings (then verify with a live clock).

Quick takeaway

Use timezone names (ET/CT/MT/PT or the IANA form like America/Los_Angeles) and confirm with a live clock. This prevents mistakes when daylight saving rules change.

Practical windows that usually work

A common approach is to aim for late morning to early afternoon in the US reference timezone. That tends to overlap with business hours across multiple states. Then confirm with the live clock pages.

Checklist before you send the invite

  • Write the timezone in the subject line.
  • Add a second reference time if your audience is international.
  • Link to the relevant state page for a one-click confirmation.
