You can say exactly which day that was 🤓🕰

The Zimmer Tower, originally the Cornelius Tower, was once part of the city's fortifications in the 14th century. In 1928, the astronomer and clockmaker Louis Zimmer gave the city of Lier his clock mechanism "de Jubelklok", which shows various times and astronomical events, to mark the upcoming 100-year anniversary of Belgium's independence.

1. Phases of the Moon:
Displays the current phase of the moon, such as new moon, first quarter, full moon, or last quarter.

2. Metonic Cycle and Epact:
The Metonic Cycle is a 19-year period after which the phases of the moon repeat on the same days of the year. The Epact is the number of days by which the lunar year differs from the solar year.

3. Equation of Time:
Shows the difference between solar time (as shown by a sundial) and clock time, accounting for the Earth's elliptical orbit and axial tilt.

4. Zodiac:
Indicates the current zodiac sign, which is determined by the position of the sun relative to the twelve constellations of the zodiac throughout the year.

5. Solar Cycle and Dominical Letter:
The Solar Cycle is a 28-year cycle used in the Julian and Gregorian calendars. The Dominical Letter is a system for determining the day of the week for any given date in a year.

6. Week:
Displays the current day of the week.

7. Globe:
Shows a representation of the Earth, indicating the current position of the sun relative to the Earth.

8. Months:
Indicates the current month of the year.

9. Calendar Days:
Displays the current day of the month.

10. Seasons:
Shows the current season (spring, summer, autumn, winter).

11. Tides:
Indicates the state of the tides, which are influenced by the gravitational pull of the moon and the sun.

12. Age of the Moon:
Shows the number of days since the last new moon, indicating the moon's age in its current lunar cycle.

Another astronomical clock, "de Wonderklok", has been located in an annex to the Tower. The clock mechanism contains, among many other displays, the slowest rotating hand in the world.🐌
