◊ common questions

Quick answers. Before you book the call.

What's the time difference between San Juan and Kuala Lumpur?

San Juan is 12 hours ahead of Kuala Lumpur. San Juan runs on GMT-4 and Kuala Lumpur on GMT+8. 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 San Juan from Kuala Lumpur?

About 17,266 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 20h 49m, not counting airport time, winds, or routing around restricted airspace.

Can I send this meeting time as a calendar invite?

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 San Juan and Kuala Lumpur use?

San Juan uses the United States dollar (USD, $); Kuala Lumpur uses the Malaysian ringgit (MYR, RM). Check the live rate before transferring money or paying with a card abroad — most banks add a 1–3 % FX margin on top of the mid-market rate.

How do I call San Juan from Kuala Lumpur?

Dial the international prefix used by your carrier (often 00), then +1, 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.

What language is spoken in San Juan and Kuala Lumpur?

Both Puerto Rico and Malaysia count English among their official languages, so business meetings often skip translation. San Juan also has Spanish; Kuala Lumpur adds Malay.

Do San Juan and Kuala Lumpur drive on the same side of the road?

No. Puerto Rico drives on the right, Malaysia on the left. If you're renting, expect a learning curve on the first day — especially at roundabouts and when judging the centre of the lane.
