## Questions & Answers

**Q: How long did the calendar last?  A week, month, year?   (Before it stopped working).**
A: The calander is good until 2040. Since there aren't a lot of moving parts, it will likely get lost before it's damaged.

**Q: Is there a video explaining how to use the perpetual calendar?  The "how to play" and "leap year query" in the instruction book aren't exactly clear.**
A: There's should be a link if you scan the qr code in the book

**Q: If I lightly use metallic spray paint before I pop the pieces out, dry, then assemble would it work?**
A: My clock would not work long as to much friction so I would not do it on the parts that need to move

**Q: How long does the perpetual calender stay in time?**
A: 2018 -2040.
