Stop Doing the Time Zone Maths in Your Head — Use This Instead

If you work with clients or colleagues across different countries, you have probably spent more time than you'd like mentally calculating what time it is somewhere else. If it's 10am in Amsterdam, what time is it in Sydney? And what about that third person calling in from New York?

There is a free tool that removes all of that friction: the Meeting Planner by timeanddate.com. You simply select a date and up to three cities, and it shows you a clear side-by-side overview of all the time zones — colour-coded to indicate what counts as working hours, office hours, and the middle of the night. No calculating, no guessing, no accidental 6am calls. It also accounts for daylight saving time automatically, which anyone who has ever been caught out by a clock change mid-meeting will appreciate.

I use it regularly when coordinating between Amsterdam and Sydney. It takes about ten seconds and saves a small but real amount of mental energy every single time. Bookmark it — you'll wonder how you managed without it.
