Show HN: Modern meetings scheduling tool in different time zones (timewiz.cc)

Hi, HN!

I use the World Time Buddy app a lot in my work. While it's a great tool, it's showing its age – the annoying page reloading when changing the date and the lack of a dark theme are inconvenient in the evening.

Hence, I've developed a modern alternative that addresses these issues. I trust it will prove beneficial to others as well. Any feedback or suggestions for enhancing the product are greatly appreciated.
