Correct way to state time on invitation?

When stating time on an invitation, use a clear and consistent format, such as "Saturday, June 10, 2023, at 3:00 PM." It's best to specify whether the time is in the morning or evening, especially if it could be ambiguous. For formal events, you might consider using "half past" or "a quarter to" instead of numerical times. Always include the time zone if your guests are coming from different locations.
