Use one of the following formats: 10:30AM-5PM or 10:30-17:00. It can be assumed that time is in the local timezone.

Use "noon" and "midnight", not 12AM or 12PM or 00:00.

Note:

  • In 12-hour format, minutes not shown when not required, e.g., 5PM, not 5:00PM.
  • In 24-hour format, always show minutes, e.g., 17:00, not just 17.
  • Where minutes are shown, use a colon as the separator, e.g., 17:30, not 17.30 or 17-30.
  • Spaces and periods (fullstops) should be left out, e.g., 10:30AM-5PM, not 10:30 A.M. – 5 P.M.
  • Spaces should be left out for noon and midnight too, e.g., 10AM-noon.
  • Choose between 12- and 24-hour formats by following predominant local usage. Ask yourself: which format will visitors see in newspapers, on shop doors, and on train schedules?
  • If using 24-hour format, make sure that's clear; if there are no times after noon, consider using the 12-hour format (with the "AM") to avoid confusing readers expecting a 12-hour format.

  • Spaces should be left out, e.g., M-F not M - F or M thru F.
  • Leave the dash out for a pair of days, e.g., Sa Su not Sa-Su.
  • When combining days with time, put the days first, e.g., M-F 10AM-2PM rather than 10AM-2PM M-F.
  • For all seven days, use "daily". Do not use "every day" or "Su-Sa".
