Schedule Cross-Timezone Meetings
Find meeting times that work across multiple timezones without anyone joining at 3 AM.
Calculate Business Hours Overlap
Find the overlapping business hours between offices or teams in different timezones.
ToolWhen teams are spread across timezones, the overlap window -- the hours when everyone is at work simultaneously -- determines how much real-time collaboration is possible. A 2-hour overlap is enough for a standup and quick sync. Zero overlap means purely async work.
Convert business hours (typically 9-5) from each location to a common reference and find the intersection. Use timezone_info to understand UTC offsets and DST rules that affect the overlap. This is critical for staffing decisions, SLA coverage planning, and setting expectations for response times.
