Time Zone Guide for Remote Teams — US, UK, India, Australia (2026)
A remote team spanning New York, London, Bangalore, and Sydney operates across roughly 13.5 hours of time zone spread. There is no single meeting time that's convenient for everyone. This guide covers the current offsets, where overlap exists, how to structure recurring meetings, and when to go fully asynchronous.
Current Time Zone Offsets (Winter / Standard Time)
New York (EST): UTC−5
London (GMT): UTC+0
Bangalore / Mumbai (IST): UTC+5:30
Sydney (AEDT): UTC+11
Spread: New York to Sydney = 16 hours apart in winter
US–UK Overlap Window
The US East Coast and UK have a comfortable 5-hour standard time offset (4 hours during US/UK summer when both observe DST). Working hours overlap from roughly 1:00 PM–5:00 PM GMT / 8:00 AM–12:00 PM EST.
This is the most natural overlap in the four-location setup. Most US–UK calls can be scheduled in the US morning without anyone taking an unusual slot.
US–India Overlap Window
India is 10.5 hours ahead of New York (EST) in winter. The two locations have almost no overlap during normal business hours.
Best window: 8:00–10:00 AM EST = 6:30–8:30 PM IST. India is wrapping up; East Coast is starting. West Coast (PST) teams need to join at 5:00–7:00 AM for the same window — which is why India–West Coast synchronous collaboration is particularly difficult.
US–Australia Overlap Window
Sydney is 16 hours ahead of New York in winter. There is essentially no overlap during normal business hours. The only viable synchronous window involves someone working outside their normal hours.
Possible window: 7:00–9:00 AM EST = 11:00 PM–1:00 AM AEDT. Very late for Australia. Alternatively, 7:00–9:00 PM EST = 11:00 AM–1:00 PM AEDT — evening for the US, which can work for brief syncs.
UK–India Overlap Window
London and Bangalore have a 5.5-hour gap in winter. Best window: 12:00–2:00 PM GMT = 5:30–7:30 PM IST. This is comfortable for the UK (afternoon) and acceptable for India (early evening). UK–India synchronous collaboration is easier than US–India.
India–Australia Overlap Window
Bangalore (IST, UTC+5:30) and Sydney (AEDT, UTC+11) are 5.5 hours apart in summer. Best window: 9:00–11:00 AM IST = 2:30–4:30 PM AEDT. This works well for both — morning India, afternoon Sydney.
How DST Changes Affect Your Team Offsets
DST changes are the biggest source of scheduling confusion for international teams. The problem: the US, UK/EU, and Australia all change clocks on different dates, and India never changes at all.
There are up to four different offset configurations throughout the year depending on which combination of countries has changed. During transition weeks, calendar invites that were set months in advance may show the wrong time in one location.
DST Transition Weeks to Watch in 2026
March 8, 2026: US springs forward (UK/EU haven't yet) — US–UK gap shrinks to 4h for 3 weeks
March 29, 2026: UK/EU spring forward — full summer offsets resume
October 4, 2026: Australia falls back — India–Australia gap shrinks
November 1, 2026: US falls back — US–India gap grows back to 10.5h
Recommended Meeting Structure for Four-Zone Teams
Weekly all-hands: Schedule at the US East Coast morning window (8–9 AM EST / 1–2 PM GMT / 6:30–7:30 PM IST). Australia joins asynchronously via recording unless a live presence is essential.
US–UK syncs: 9–11 AM EST / 2–4 PM GMT — natural overlap, no one takes an unusual slot.
India–Australia syncs: 9–11 AM IST / 2:30–4:30 PM AEDT — comfortable for both.
US–India or US–Australia one-on-ones: Rotate the inconvenient slot. If week 1 is early morning for the US person, week 2 should be late evening. Neither side should always take the uncomfortable time.
When to Go Async Instead
Not every communication needs a live meeting. Async works well for:
Status updates — use Loom videos or written summaries. A 2-minute Loom is more efficient than a 30-minute catch-up call that requires three people to adjust their schedules.
Reviews and approvals — use tools with commenting (Figma, Notion, GitHub PRs). Set a 24-hour response SLA so work doesn't stall waiting for overlapping hours.
Routine Q&A — Slack or Teams with clear channel ownership. India and Australia can leave questions before signing off; US and UK answer when their day starts.
Tools for Managing Multi-Zone Teams
World Clock: Keep a persistent world clock widget showing all four locations. iFormat's time zone converter lets you check 'what time is it in all four cities right now' without mental arithmetic.
Every Time Zone (everytimezone.com): Shows all four zones as a scrollable band — drag to a time in your zone to see what it is everywhere else.
Google Calendar time zone settings: Set your secondary time zone to the location you communicate with most often. The calendar shows two time columns, removing the conversion step for every event.
Reclaim.ai / Clockwise: AI scheduling tools that protect focus blocks and find meeting times that work across zones automatically.
Frequently Asked Questions
What is the best meeting time for US, UK, and India?
8:00–10:00 AM EST / 1:00–3:00 PM GMT / 6:30–8:30 PM IST is the most practical window. Australia cannot join without someone working unusual hours — record the meeting for async viewing.
Does India observe Daylight Saving Time?
No. India stays at IST (UTC+5:30) all year. This means the India–US and India–UK offsets change twice a year when those countries change their clocks.
How do I stop missing meetings due to DST changes?
Always create calendar invites in a specific time zone (e.g. 'EST' or 'GMT') rather than using a relative local time. Modern calendar apps convert automatically. Flag transition weeks in your team calendar so everyone knows the offsets are shifting.
