Meeting planner

Add up to four cities and compare every hour of the day side by side. Tinted cells are business hours (9:00–17:00), pale cells are waking hours, and dark cells are night. Columns outlined in the accent colour work for everyone.

No hour is within business hours in every city. Consider rotating meeting times, or letting one side join early or late — our guide to scheduling across time zones has practical tactics.

How to read the grid

Each column is one hour of the day, counted in UTC so every row lines up on the same moment. Each row shows what that moment looks like on the clock in one city, using the official time zone rules for the date you picked — daylight saving included. Look for the outlined columns: those are the hours when nobody has to wake up at dawn or stay up past midnight.
