Why people convert PET to Mexico time
- Scheduling a call from PET to Mexico: a 10:00 AM start in PET lands at 9:00 AM in Mexico, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both PET and Mexico are inside the 9-to-5 working day between 10:00 AM and 5:00 PM PET time (9:00 AM–4:00 PM CST). That is roughly 7 hours of usable overlap.
- Watching a live event or market open: PET viewers need 8:00 AM in Mexico to catch a 9:00 AM start there, and 1:00 AM if the event is anchored to PET.
- Always state the zone abbreviation, not just the hour. "3:00 PM PET" is unambiguous; "3 PM" across a -1h gap is not.
- Block 10:00 AM–5:00 PM PET as the recurring meeting window if you work primarily from PET and need Mexico colleagues present.
