Figure 1. August 18, 2024: house without a sundial (see Figure 3).
Figure 2. Master Miljan at the beginning and end of the work in 37°C heat.
Figure 3. Belgrade, August 18, 2024, Solar Noon (apparent noon): The house with a sundial. In the future, this house won’t need an address; simply saying House with a sundial on Voždovac will be enough.
Figure 4. Belgrade, August 18, 2024, PIN dialogue:
Irina: – What time is it?
Petra: – The shadow will tell you.
Irina: – What about when it’s cloudy?
Petra: – When there’s no sun, the sundial remains silent.
Natalia: (Does not speak, agrees).
Figure 5. Belgrade, August 18, 2024, dialogue in front of the PIN-sundial:
Person A: – Is the sundial accurate?
Person B: – No… it’s about 3-4 minutes behind?!
Person A: – Perfect, that means it’s working just right.

(Note. The sundial’s accuracy is subject to the equation of time (e): August 18. 2024, e = –3 min 46 s).
Figure 6. Masters Darko and Miljan, after completing the work, leave satisfied, having confirmed the sundial’s accuracy and ready to add sundial installation to their CVs.
