Why people convert MDT to PDT time

  • Scheduling a call from MDT to PDT: a 10:00 AM start in MDT lands at 9:00 AM in PDT, so you can confirm the slot without doing the arithmetic yourself.
  • Finding shared working hours: both MDT and PDT are inside the 9-to-5 working day between 10:00 AM and 5:00 PM MDT time (9:00 AM–4:00 PM PDT). That is roughly 7 hours of usable overlap.
  • Booking travel or deliveries: tracking PDT local time against MDT keeps pickup windows and arrival estimates honest across the -1h offset.
  • Always state the zone abbreviation, not just the hour. "3:00 PM MDT" is unambiguous; "3 PM" across a -1h gap is not.
  • Block 10:00 AM–5:00 PM MDT as the recurring meeting window if you work primarily from MDT and need PDT colleagues present.
