Why people convert Mexico to PET time
- Scheduling a call from Mexico to PET: a 10:00 AM start in Mexico lands at 11:00 AM in PET, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Mexico and PET are inside the 9-to-5 working day between 9:00 AM and 4:00 PM CST time (10:00 AM–5:00 PM PET). That is roughly 7 hours of usable overlap.
- Booking travel or deliveries: tracking PET local time against Mexico keeps pickup windows and arrival estimates honest across the +1h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM CST" is unambiguous; "3 PM" across a +1h gap is not.
- Block 9:00 AM–4:00 PM CST as the recurring meeting window if you work primarily from Mexico and need PET colleagues present.
