Frequently Asked Questions
Details on daylight saving adjustments, calendar compatibility, and timezone calculations.
How does the planner account for Daylight Saving Time (DST)?
The tool uses your browser's native JavaScript Intl.DateTimeFormat API and the IANA Time Zone Database. All daylight saving shifts are automatically and precisely accounted for in real time.
Can I copy meeting time summaries for calendar invites?
Yes! Clicking 'Copy Meeting Invite' generates an elegant markdown summary displaying the chosen meeting time converted into each team member's local time zone.
Are my scheduled meeting details sent to any server?
Zero server requests are made. All time calculations, city lists, and invitation formats execute exclusively in your device's browser memory.
