About the Meeting Time Planner

The ByteTools Meeting Time Planner lays out a full day side by side for every time zone on your call. Add the cities your colleagues work in, pick a date, and the grid shows what the clock reads in each place for all 24 hours — with each person's working hours shaded so the overlap is obvious at a glance.

Hours outside a person's working window are dimmed, so you can see immediately that 15:00 London is fine for New York but brutal for Sydney. Click any column to pin it and read the exact local date and time for every zone on the list.

Time zones come from your browser's own IANA database via Intl.DateTimeFormat, which means daylight saving transitions are applied correctly for the date you choose rather than assumed from a fixed offset. No network calls are made and nothing is uploaded.

Frequently asked questions

How do I find a meeting time that works across time zones?

Lay every participant's day out on the same grid and look for hours that fall inside everyone's working window. This planner highlights those columns for you, so the workable slots — and the fact that there are sometimes none — become obvious immediately.

Does this handle daylight saving time correctly?

Yes. It uses your browser's built-in IANA time zone database through Intl.DateTimeFormat, so the offset applied is the one actually in force on the date you pick. That matters because the US, Europe and Australia switch on different dates, and some zones never switch at all.

Why do the offsets between two cities change during the year?

Because daylight saving start and end dates differ by region. London and New York are normally five hours apart, but for a couple of weeks each spring and autumn they are four or six, which is when cross-Atlantic meetings mysteriously shift.

What are good working hours to assume for a meeting?

Nine to five local time is the common default and what this tool starts with, but it is editable per row because expectations vary. If you regularly work across Asia and the Americas, agreeing an explicit shared window beats guessing.

Why does one row show a different date?

Because a single instant can fall on different calendar days around the world. The grid marks columns where a zone is a day ahead or behind, which prevents the classic mistake of inviting someone to a Tuesday meeting that is Wednesday morning for them.
