❓ Frequently Asked Questions
What is the difference between solar, lunar, and lunisolar calendars?
Solar calendars track Earth's orbit around the Sun; lunar calendars follow Moon phases; lunisolar calendars combine both, using adjustments like leap months to stay aligned with seasons.
What is 'sacred time' and how is it observed in many traditions?
Sacred time refers to periods set apart for religious observance—weekly rest, holy days, and festivals—often marked by rituals, prayer, fasting, or ritual meals.
What is a leap year and why is it used?
A leap year adds an extra day (February 29) to keep the calendar in sync with the solar year, preventing drift over time.
What are common timekeeping devices and what do they measure?
Sundials use shadows in daylight; water clocks measure time by the steady flow of water; mechanical clocks use gears and springs; atomic clocks rely on stable atomic transitions for precision.
