Time zone overlap with India from Europe, the UK, and Australia

"Will the time zones work?"

This is the question that comes up on every call. It comes from founders in London, Amsterdam, Stockholm, and Melbourne who want a team in India but aren't sure whether they'll actually be able to work together during normal hours.

The short answer: yes, and it's easier than most people expect. Here are the specific windows.

India Standard Time, briefly

India runs on a single time zone: IST, which is UTC+5:30. Unlike most countries, India doesn't observe daylight saving time, so the offset stays constant year-round.

This matters because European, UK, and Australian time zones shift with daylight saving time, which means the overlap window changes slightly between summer and winter. The numbers below account for both.

Europe (CET/CEST): 4 to 5.5 hours of overlap

Central European Time covers the Netherlands, Germany, France, Sweden, Denmark, Norway, and most of Western and Northern Europe.

Winter (CET, UTC+1): IST is 4.5 hours ahead. A team member working 9:30 AM to 6:30 PM IST overlaps with your 10:00 AM to 2:00 PM CET. That's roughly 4 hours of synchronous time.

Summer (CEST, UTC+2): IST is 3.5 hours ahead. The same IST working hours overlap with your 11:00 AM to 3:00 PM CEST. Still roughly 4 hours, shifted later in your day.

With a shifted schedule: If your team member starts at 11:00 AM IST instead of 9:30 AM, they work until 8:00 PM IST and overlap with your 11:30 AM to 4:30 PM CET (winter) or 12:30 PM to 4:30 PM CEST (summer). That's 4.5 to 5 hours of sync time, covering your entire afternoon.

For most European companies, the 4-to-5-hour overlap window is more than enough for a daily standup, a feedback session, and collaborative work. The hours before the overlap (when India is working and Europe hasn't started yet) are productive focus time for your team member.

United Kingdom (GMT/BST): 4.5 to 5.5 hours of overlap

Winter (GMT, UTC+0): IST is 5.5 hours ahead. A standard 9:30 AM to 6:30 PM IST schedule overlaps with your 9:00 AM to 1:00 PM GMT. Roughly 4 hours.

Summer (BST, UTC+1): IST is 4.5 hours ahead. The same IST hours overlap with your 10:00 AM to 2:00 PM BST. Still roughly 4 hours.

With a shifted schedule: Starting at 11:00 AM IST extends the overlap to 5 to 5.5 hours with UK afternoon hours.

UK companies frequently run daily standups at 9:30 or 10:00 AM UK time. A team member in India can comfortably attend a 10:00 AM GMT standup (3:30 PM IST) with plenty of working hours remaining.

Australia (AEST/AEDT): 4.5 to 5.5 hours of overlap

This one surprises people. The Australia-India overlap is strong.

Winter (AEST, UTC+10, April to October): IST is 4.5 hours behind. A standard 9:30 AM to 6:30 PM IST schedule overlaps with your 2:00 PM to 11:00 PM AEST. In practice, the useful overlap is roughly 2:00 PM to 6:00 PM AEST (your afternoon) against 9:30 AM to 1:30 PM IST (their morning). That's 4 hours.

Summer (AEDT, UTC+11, October to April): IST is 5.5 hours behind. The same IST hours overlap with your 3:00 PM to midnight AEDT. The useful window is 3:00 PM to 6:30 PM AEDT against 9:30 AM to 1:00 PM IST. Roughly 3.5 hours, or more if your team works slightly later.

With a shifted schedule: If your India team starts at 7:00 AM IST (which some roles can accommodate), the overlap with Australian morning hours extends significantly.

For Australian companies, the overlap covers your afternoon, which works well for daily syncs, reviews, and collaborative sessions. The India team's afternoon, when Australia is asleep, becomes uninterrupted focus time.

What a typical day looks like

Here's a concrete example for a founder in Amsterdam working with an EA in India.

9:30 AM IST / 6:00 AM CET: Your EA starts their day. They process overnight emails, update your calendar, follow up on pending tasks, and prepare a summary of what needs your attention.

10:00 AM CET / 2:30 PM IST: You start your day. The summary is in your inbox. You review it, respond to questions, and set priorities for the rest of the day.

10:30 AM CET / 3:00 PM IST: Daily check-in (15 minutes). You align on priorities, flag anything urgent, answer questions.

11:00 AM to 2:00 PM CET / 3:30 PM to 6:30 PM IST: Collaborative window. Slack messages get real-time responses. Quick calls when needed. Feedback on work in progress.

2:00 PM CET / 6:30 PM IST: Your EA's day ends. Any tasks assigned during the overlap are either done or queued for tomorrow morning.

2:00 PM to 6:00 PM CET: You work on client calls, sales, and strategy. Your EA's output from the day is available for review.

The pattern is simple: they start before you, handle prep work, you overlap for 3 to 4 hours of synchronous collaboration, then you each have uninterrupted focus time.

Async vs sync: it's both

The best remote teams don't run entirely synchronously or entirely asynchronously. They use the overlap for high-bandwidth communication (standups, feedback, quick decisions) and the non-overlap for deep work.

For roles like design, content writing, development, and data analysis, the async hours are a feature, not a bug. Your designer gets a brief during the overlap, works on it during their remaining hours, and you review it when you start the next morning. The feedback cycle runs on a natural 24-hour rhythm.

For roles like executive assistants and customer support, more synchronous overlap is useful. Adjusting the working schedule by an hour or two in either direction can add an extra hour of overlap without straining anyone.

How to set this up

The working schedule is one of the first things discussed during the scoping call. Based on your location, your working hours, and the role, the team works with you to define the schedule that creates the right balance of overlap and focus time.

Most companies settle on a schedule within the first week and rarely change it after that. The India team member's working hours are set, consistent, and respected.

Common concerns addressed

"What if I need them outside the overlap?" For urgent issues, Slack messages work. Most team members check notifications shortly after their working hours start and can flag urgent items. For truly time-sensitive roles, the schedule can be shifted further to maximize overlap.

"What about meetings with clients in my time zone?" Your team member can join client meetings that fall within their working hours. Meetings outside those hours should be the exception, not the norm.

"Does India observe daylight saving time?" No. IST stays at UTC+5:30 year-round. The overlap shifts slightly when your time zone changes, but it's predictable and easy to plan around.
