📊 Global Business Overlaps

Finding a common meeting time is the biggest challenge for remote teams. Use these "Golden Hours" for scheduling:

• NY & London
  8:00 AM - 12:00 PM (EST) is the prime window.
• London & Tokyo
  8:00 AM - 10:00 AM (GMT) allows a brief overlap.
• NY & Sydney
  4:00 PM - 6:00 PM (EST) often catches the Australian morning.

⏱️ Understanding Time Zones

The world is divided into 24+ time zones based on the Earth's rotation relative to the sun.

• UTC (Coordinated Universal Time): The primary time standard by which the world regulates clocks. It is effectively the successor to GMT.
• Prime Meridian: The line of 0° longitude runs through Greenwich, England.
• Offsets: Local time is defined as positive (+) or negative (-) hours relative to UTC. (e.g., India is UTC+5:30).

☀️ Daylight Saving Time (DST)

Many regions adjust clocks to extend daylight in the evening.

• Spring Forward: Clocks move forward 1 hour (losing an hour of sleep) to start DST.
• Fall Back: Clocks move back 1 hour (gaining an hour) to end DST.
• Impact: Be careful when scheduling meetings in March/October, as countries switch on different weeks.
