Common mistakes with Los Angeles and Denver

  • Assuming the gap is fixed. Both cities change their clocks, but not on the same weekend, so a recurring meeting can land an hour off for a few weeks.
  • Writing “PST” all year for Los Angeles. In summer the zone is Pacific Daylight Time; calendar apps handle it, but a typed time in an email can be read the wrong way.
