Working Across Time Zones: A Guide for Remote Teams
How to schedule meetings between Kuwait, Europe and the US, understand PST, CST and EST, handle daylight saving time and avoid costly mix ups.
Remote work and global clients mean that a “quick call at 10” can mean four different times to four different people. Time zone mistakes cause missed meetings, late deliveries and frustrated clients. With a few simple habits, working across time zones becomes routine.
Time zone basics
Every time zone is set a number of hours ahead of or behind Coordinated Universal Time (UTC). Kuwait, Saudi Arabia, Iraq and Qatar are 3 hours ahead of UTC all year round. The UAE and Oman use UTC+4. London uses UTC+0 in winter and UTC+1 in summer. The mainland United States has four main zones:
- Eastern Time (ET): New York, Washington and Miami, 5 hours behind UTC in winter and 4 in summer.
- Central Time (CT): Chicago, Dallas and Houston, 6 hours behind UTC in winter and 5 in summer.
- Mountain Time (MT): Denver, 7 hours behind UTC in winter and 6 in summer. Most of Arizona does not change its clocks.
- Pacific Time (PT): Los Angeles, San Francisco and Seattle, 8 hours behind UTC in winter and 7 in summer.
Daylight saving time: the source of most mistakes
Many countries move clocks forward one hour in spring and back in autumn, but not on the same dates. The United States changes on the second Sunday of March and the first Sunday of November; the European Union changes on the last Sundays of March and October. Kuwait and most Gulf countries do not change at all.
This means the difference between Kuwait and New York is 8 hours in winter but 7 hours in summer. And for a few weeks each spring and autumn, Europe and the US are briefly out of sync. Always check the specific date when scheduling ahead. Everytoool’s PST to EST and CST to EST converters apply daylight saving automatically for the date you choose, and you can switch either side to Kuwait, Dubai, London or other cities.
Finding overlapping working hours
Overlap is the window when everyone is reasonably at work. A few examples:
- Kuwait and London: 2 to 3 hours apart. Plenty of overlap in the morning and early afternoon.
- Kuwait and New York: 7 to 8 hours apart. The overlap is roughly 4 to 6 PM in Kuwait (9 to 11 AM in New York).
- Kuwait and California: 10 to 11 hours apart. Very little overlap; early morning in California is evening in Kuwait.
- New York and Los Angeles: always 3 hours apart. Afternoons in New York align with mornings in LA.
Rotate inconvenient meeting times fairly so the same people are not always joining late at night.
Habits that prevent mistakes
Always write the time zone
Never write “Let’s meet at 3”. Write “3:00 PM Kuwait time (8:00 AM ET)”. Including both times removes ambiguity.
Use calendar invitations
Calendar apps convert invitations to each attendee’s local time automatically. Make sure your own calendar is set to the correct time zone, especially when travelling.
State deadlines with a time zone
“Due Friday” could mean Friday morning in Kuwait or Friday night in California. A 21 hour difference. Write “Friday 5:00 PM ET”.
Be careful near midnight
A late evening meeting in one zone may fall on the next day elsewhere. Double check the date as well as the time.
Know the work week
Kuwait and most Gulf countries work Sunday to Thursday, while the US and Europe work Monday to Friday. Effectively, there are only four shared working days a week. Plan important deadlines and meetings for Monday to Thursday.
Counting days and deadlines
Contracts and projects often specify periods such as “30 days” or “10 business days”. Use a date calculator to count exactly, and remember that business day counts usually exclude weekends but not public holidays, which differ between countries.
Tools and practices for distributed teams
- Share a simple table of team members’ cities, time zones and working hours.
- Prefer asynchronous updates (written summaries, recorded videos) to reduce the need for meetings.
- Record important meetings for those who cannot attend.
- Agree on a “core hours” window where everyone is available.
- Use UTC in technical logs and systems to avoid confusion.
Summary
Time zones are manageable when you write times explicitly, let calendars convert for you, watch out for daylight saving changes and respect colleagues’ working hours. A ten second check with a converter can prevent a missed meeting with an important client.
