Australia’s 2001 Millennium celebrations marked the arrival of the new millennium with grand festivities across major cities. Fireworks illuminated iconic landmarks like the Sydney Harbour Bridge, and gatherings brought people together in celebration.

The Gregorian calendar is the calendar system most widely used today. Introduced by Pope Gregory XIII in 1582 to correct inaccuracies in the older Julian calendar, it redefined leap years to maintain better alignment with the solar year. In the Gregorian system, a year typically has 365 days, with a leap year adding an extra day every four years, except for century years not divisible by 400. This system improved accuracy in calculating seasons and equinoxes, influencing global timekeeping, religious observances, and civil events.
