Visual Timezone Converter & Meeting Planner

Scheduling meetings across multiple timezones is one of the most frustrating aspects of remote work. Calculating time differences manually often leads to missed meetings, confusion over Daylight Saving Time (DST), and scheduling accidents. A visual timezone converter completely eliminates this friction by aligning times side-by-side.

How to use the Global Meeting Planner

Our tool allows you to add multiple global cities and visually slide a meeting time across the board. The color-coded interface immediately highlights overlapping business hours across all selected regions, ensuring you don't schedule a meeting while your colleagues in Tokyo or London are asleep.

Why is time so complicated in software?

Timezones are a notoriously difficult problem in computer science. Different regions observe Daylight Saving Time on different dates, some timezones are offset by 30 or 45 minutes (rather than full hours), and governments occasionally change their timezone boundaries. DevvTools uses the standard IANA Time Zone Database to ensure every conversion you make is cryptographically precise and historically accurate.
