Why time zones matter more than you think
When you work remotely for clients on several continents, your location is no longer only a lifestyle choice. It also determines how many hours you can talk to the people who pay you. If you live eight hours away from your main client, you may spend your life in meetings at night or in the early morning, or you may only ever communicate by email.
The good news is that you do not need a perfect time zone. You need enough overlap with the people you must meet, and you need habits that make the rest of the day productive. This guide explains how to think about overlap, which regions work best for different client mixes, and how to manage the inevitable awkward calls.
The key idea: overlap hours
Most people work roughly 9 am to 6 pm. If you and a client both work those hours in different time zones, the overlap is what remains once you convert them to a shared clock.
For example, London and New York are five hours apart. A 9 to 6 day in London is 4 am to 1 pm in New York, so the overlap with a normal New York day (9 am to 6 pm) is only 9 am to 1 pm, or four hours. Berlin and Singapore are six or seven hours apart, depending on daylight saving, and share a few hours in the late morning in Europe and the early evening in Asia.
A practical target is three to four hours of shared working time with your most important clients. Beyond that, extra overlap is useful but not essential.
Step one: map your clients
Write down where your main clients, colleagues or managers are, and when they are available. Then check what the overlap would be from the places you are considering.
- List each client with their city and normal working hours.
- Convert those hours into UTC.
- Convert them into the time zone of each potential base.
- Count the overlapping hours and mark early starts or late finishes.
This takes ten minutes and prevents expensive mistakes. A location that looks perfect on paper can mean 11 pm calls three times a week.
Western Europe and the Atlantic islands (UTC+0 to UTC+1)
Portugal, the UK, Ireland, Spain and the Canary Islands sit in a sweet spot for global work.
- With the US East Coast (UTC-5): Five or six hours apart, so the morning in the US overlaps with your afternoon. You will usually have three to four hours of overlap, from about 2 pm to 6 pm local time.
- With the US West Coast (UTC-8): Eight or nine hours apart, so overlap is shorter, usually only the early evening in Europe.
- With Asia (for example Singapore, UTC+8): Seven or eight hours apart. You can speak to Asia in your morning, which is their afternoon or evening.
This is why Lisbon, Madeira and the Canary Islands are so popular with remote workers. They are close to European clients and have workable overlap with both coasts of the US.
Central and Eastern Europe, Turkey and the Middle East (UTC+1 to UTC+4)
These regions are well placed for Europe, the Middle East and India, and reasonable for East Asia in the morning.
- With the US East Coast: Six to eight hours apart. Overlap is limited to your afternoons and evenings.
- With India (UTC+5:30): Easy, since the difference is a few hours.
- With Singapore or Hong Kong: Four to six hours, so overlap in your morning.
Tbilisi, Istanbul and Dubai are popular bases for people serving clients across Europe and Asia.
Latin America (UTC-3 to UTC-6)
Mexico City, Bogotá, Medellín, Lima and Buenos Aires share working hours with the US almost exactly, which is why they are so popular with US-based remote workers.
- With the US: Excellent, with overlap across the entire working day.
- With Europe: Good in the morning, when European clients are at the end of their day.
- With Asia: Difficult, since you are 12 to 14 hours apart.
If most of your clients are American, this is hard to beat.
Southeast Asia and Australia (UTC+7 to UTC+10)
Bangkok, Bali, Chiang Mai, Kuala Lumpur, Singapore and Sydney suit workers with Asian or Australian clients.
- With Asia-Pacific: Excellent.
- With Europe: Your late afternoon and evening overlap with the European morning, though you may need to work late.
- With the US: Very difficult. You are 12 to 16 hours apart, which usually means working at night.
Many people based in Southeast Asia keep a split schedule: a long focused morning, a break, and then evening calls.
Sample days in different bases
These examples assume a 9 to 6 day for the clients.
Lisbon-based, clients in New York and London:
Start at 8 am with deep work. Meet London in the morning. Take a long lunch. Meet New York between 2 pm and 6 pm. Finish by 7 pm.
Mexico City-based, clients in New York and Berlin:
Meet Berlin early, at 7 or 8 am. Work independently late morning. Meet New York in the afternoon. Done by 5 pm.
Bangkok-based, clients in Singapore and London:
Meet Singapore in the morning. Take a long afternoon break. Meet London in the evening, at 6 to 8 pm local time. Finish by 9 pm.
Managing awkward hours
Even in a good base, someone usually has to take a difficult hour. These habits keep the cost manageable.
- Share your hours. Put your working hours and time zone in your email signature and calendar.
- Offer a rotating schedule. If you meet a team across continents, alternate the meeting time so no one always loses.
- Use asynchronous updates. Short recorded videos, written summaries and shared documents reduce the need for live meetings.
- Batch meetings. Concentrate calls on certain days so that you can protect deep work on others.
- Always write the time zone when scheduling, and use a calendar tool that shows conversions.
- Protect your sleep. Regular calls at midnight or 5 am harm your health and your work. If you cannot avoid them for long periods, consider a different base.
Daylight saving: the hidden trap
Daylight saving time starts and ends on different dates in different regions. In the US it changes in March and November, and in Europe in late March and late October. For a few weeks each year, the gap between time zones differs by an hour, and meetings you have held for months suddenly shift.
Check your calendar every spring and autumn, and tell clients in advance if your availability changes. Some countries, such as Thailand, India and Japan, do not use daylight saving, so their relationship with Europe and the US changes twice a year.
Tools that help
- A world clock widget on your phone or computer, with your key cities.
- Calendar apps that display multiple time zones side by side.
- Scheduling tools that let clients choose a time in their own zone.
- Project management software with deadlines and clear ownership, so work continues while you sleep.
Beyond the clock
The best time zone is only useful if you like living there. Consider cost of living, internet quality, visas, climate and community. Before committing to a long stay, try a month in the new location and see how the schedule feels.
Also consider your own body. Some people are natural early risers and are comfortable with 6 am calls. Others are night owls who prefer evening meetings. Match your base to your rhythm where you can.
Frequently asked questions
Is one time zone best for everyone?
No. The best base depends on where your clients are. Western Europe, the Middle East and the Atlantic islands give the most balanced coverage if your clients are spread across continents.
Can I work across three continents?
It is possible, but one group will usually need to adapt. Be honest about your availability and agree on a regular schedule.
What if my employer requires me to be online during their hours?
Check the contract and any company policy before moving. Some employers have rules on where employees may work, for legal and tax reasons.
Do I need a visa to work remotely from another country?
Often yes. Tourist visas generally do not allow work, although the rules differ. Look at digital nomad visa options and check official sources.
A final checklist
- Map your clients and their hours.
- Convert them to your candidate time zones.
- Choose a base with at least three overlap hours with key people.
- Agree on boundaries and share your schedule.
- Recheck when daylight saving changes.
A good time zone will not make you productive, but a bad one will make everything harder. Take the time to choose well.
