Time Zone Tips & Best Practices

Essential knowledge for global time management

EST vs EDT - Daylight Saving Time DST

The US observes Daylight Saving Time from March to November. During this period, Eastern time switches to EDT (UTC-4). Always verify whether EST or EDT is in effect when scheduling international meetings.

India Time Zone Never Changes

IST (UTC+5:30) remains constant year-round since India doesn't observe Daylight Saving Time. This half-hour offset makes IST unique among major time zones.

Best Times for US-India Meetings

Optimal meeting windows: 9-11 AM EST (7:30-9:30 PM IST) or 7-9 PM EST (5:30-7:30 AM IST next day). This accommodates business hours in both regions.

Always Include UTC for Clarity

When scheduling globally, share times in UTC alongside local times (e.g., "2 PM EST / 12:30 AM IST / 7 PM UTC"). This eliminates confusion from DST transitions.

Use 24-Hour Format Internationally

To avoid AM/PM confusion across time zones, use 24-hour format (e.g., 14:30 instead of 2:30 PM) in international communications and calendar invites.
