A full day, side by side
Each row runs midnight to midnight in that city's own local time.
Hours labelled in Boston local time.
No shared hours. A standard Boston workday and a standard Sydney workday never coincide, which is why the bar above is empty. The table below shows how close the two get.

Best time to call Sydney from Boston
A standard 9:00–17:00 day in Boston does not intersect a standard day in Sydney at all. Sydney is 14 hours ahead of Boston. Whoever joins the call is stepping outside their working hours, so the fair thing is to alternate who takes the inconvenient slot.
The least disruptive options are the edges: early morning in Boston before Sydney finishes for the evening, or late afternoon in Boston once Sydney is starting the next day. Anything in the middle lands in someone's night.
Cross-timezone workday overlap and collaboration
With so little shared time, Boston and Sydney work best as an asynchronous pair with one synchronous exception. Write decisions down as they are made rather than saving them for a call, because the next chance to talk is a day away.
Treat the gap as a handoff rather than a delay. Whoever finishes first should leave the next step written down and unambiguous; 14 hours later the other side picks it up without needing to ask a question that would cost another full day.
Watch for fatigue on recurring meetings. A weekly call that sits at the very edge of someone's evening is tolerable once and corrosive after a month. If the only workable slot is uncomfortable for one side, rotate it, or accept that the meeting should be a document instead.
Practical rules for this pairing
- Rotate who takes the out-of-hours call, rather than defaulting to the same side every week.
- Move status updates into writing entirely — there is no hour where a live update is cheap for both sides.
- If the pairing is permanent, a split shift on one side buys back a real overlap.
Frequently asked questions (Boston & Sydney)
What is the current time difference between Boston and Sydney?
Sydney is 14 hours ahead of Boston. That gap is calculated from the live IANA time zone database, so it already accounts for whichever daylight-saving rules are in force today rather than assuming a fixed offset.
What is the best window for a one-hour team sync between Boston and Sydney?
There is no window where a standard 9:00–17:00 day in Boston overlaps one in Sydney, so a one-hour sync has to sit outside someone's working hours. Alternate which side absorbs it, or replace the meeting with a written handoff.
Do Boston and Sydney change their clocks on the same date?
No. Boston changes on Sun, Nov 1 and Sydney on Sun, Oct 4. Between those two dates the usual difference is off by an hour, which is the period recurring meetings quietly drift in.
How many hours do Boston and Sydney actually share in a working day?
None. A standard 9:00–17:00 day in Boston and the same in Sydney do not intersect, which is why teams spanning these two cities usually adopt a split shift on one side.
