Understanding the Astronomical Dial and Calendar

The astronomical dial is a complex map of the universe. It uses a 24-hour clock system. The outer ring shows Old Bohemian time. This time starts at sunset. The Roman numerals show the time we use today.

Look for the golden sun moving around the zodiac. It shows the sun's position throughout the year. The moon sphere is also dynamic. It rotates to show the current phase of the moon. This was incredibly advanced for the 15th century.

The calendar plate below is equally detailed. It celebrates the 12 months with seasonal activities. You can see farmers harvesting or planting. This part of the clock was added much later. It brings a touch of color to the dark stone facade.

Practical Tips for Your Prague Clock Visit

Timing is everything when visiting the Orloj. The square is busiest between 10 AM and 6 PM. If you want a front-row view, go early in the morning. A 9 AM viewing is usually much quieter. You can also visit late at night for a peaceful experience.

Watch out for pickpockets during the show. Thieves target distracted tourists looking up at the Apostles. Keep your bags in front of you. Stay aware of your surroundings in the dense crowd. This is a common tip in any Prague sightseeing guide.

If you want to take great photos, bring a zoom lens. The clock is high on the wall. A wide-angle lens is good for the whole tower. However, you need zoom for the statues. The light is best in the afternoon when the sun hits the face.

Consider buying a city pass for better value. Many passes include the Old Town Hall Tower. This can save you money if you plan to see many sites. Check the official Prague tourism portal for current prices. Always verify opening hours before your visit.
