FAQ
How do I find the best meeting time for multiple time zones?
Look for times that fall within 9 AM - 5 PM for all participants. The calculator shows business hours overlap. For teams spanning 12+ hour differences (e.g., US and Asia), overlap is minimal - consider recording meetings for async viewing.
What is UTC and why does it matter?
UTC (Coordinated Universal Time) is the world time standard. All time zones are expressed as offsets from UTC (e.g., EST is UTC-5, JST is UTC+9). It's the reference point for accurate time conversion.
How does Daylight Saving Time affect conversions?
DST changes UTC offsets by 1 hour when regions "spring forward" or "fall back". This calculator automatically accounts for DST based on the current date. Time differences between zones can change by 1-2 hours during DST transitions.
