The Meeting Optimizer is our interactive time slider that helps you find the best meeting times across multiple time zones. It color-codes availability: green for working hours (9-5), amber for evening hours (5-10), and red for sleep hours (10pm-7am).

Question 5

How accurate is the time?

Our time data is synced with IANA timezone databases and updates every minute. We account for Daylight Saving Time changes automatically across all 300+ cities.

Question 6

Can I share my dashboard with my team?

Accepted Answer

Yes! Your pinned cities are saved in your browser's local storage. For team sharing, navigate to a comparison page (like /compare/london-to-new-york) to get a shareable URL with pre-selected cities.

Question 7

What's the difference between UTC, GMT, and local time?

Accepted Answer

UTC (Coordinated Universal Time) is the global time standard. GMT (Greenwich Mean Time) is UTC+0 and used primarily in the UK. Local time is the time in your specific city, accounting for timezone offset and Daylight Saving Time.

Question 8

How do I find the best time to call someone in another country?

Accepted Answer

Add both cities to your dashboard, then use the Meeting Optimizer slider. Look for time slots where both cities show green (working hours) or amber (evening but awake). Avoid red hours where someone would be sleeping.
