◊ travel essentials

Crossing the border. Money, language, plugs.

◊ common questions

Quick answers. Before you book the call.

What's the time difference between Phnom Penh and Monterrey?

Phnom Penh is 13 hours behind Monterrey. Phnom Penh runs on GMT+7 and Monterrey on GMT-6. The gap can shift by an hour when either side enters or leaves daylight saving — the live clocks above always reflect the current offset.

When's the best time to schedule a meeting?

Standard 09:00–17:00 workdays don't intersect. Most teams compromise with one side meeting early (before 09:00) or late (after 17:00).

Does daylight saving time change the difference?

Yes, if either city observes DST. When one side shifts and the other doesn't, the gap changes by one hour. The DST badges under each clock show whether each zone is currently shifted and when the next transition lands.

How far is Phnom Penh from Monterrey?

About 15,053 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 18h 13m, not counting airport time, winds, or routing around restricted airspace.

Yes. Pick a time on the slider above, open the meeting card, customize the title and duration, then download the .ics file. It imports cleanly into Google Calendar, Outlook, and Apple Calendar with the correct timezone attached.

What currency do Phnom Penh and Monterrey use?

Dial the international prefix used by your carrier (often 00), then +855, then the local number — drop any leading zero of the city or mobile code. For free calls, WhatsApp, Signal, and FaceTime work over Wi-Fi regardless of country code.

Phnom Penh primarily speaks Khmer; Monterrey speaks Spanish. English is widely used in business contexts in major cities of both, but written contracts may need translation.
