⚡ Ultra-Fast Time
• Nanosecond (ns): Computer processing, light travel
• Microsecond (µs): Electronic circuits, high-frequency trading
• Millisecond (ms): Human reaction time, refresh rates
📅 Human Time Scale
• Second to Minute: Immediate actions
• Hour to Day: Daily activities
• Week to Month: Short-term planning
🗓️ Long-Term Time
• Year to Decade: Life phases, career planning
• Century: Historical periods
• Millennium: Civilizational timescales
⏱️ Precision Timing
Modern atomic clocks can measure time to within nanoseconds, making precise scientific measurements possible.
🌍 Time Zones
Earth is divided into 24 time zones, each representing one hour difference from UTC (Coordinated Universal Time).
📊 Leap Years
A year has 365.25 days on average. Leap years add February 29th every 4 years to account for this fraction.
