Times

  • Use figures except for noon and midnight. Use a colon to separate hours from minutes: 11 a.m., 1 p.m., 3:30 p.m.
  • Avoid such redundancies as 10 a.m. this morning or 10 p.m. tonight. Use 10 a.m. or 10 p.m. Monday, etc. as required by the norms in time element. The construction 4 o’clock is acceptable, but time listings with a.m. or p.m. are preferred.
