These are wonderful!

Thanks perilunar - I see from your profile you're a clock enthusiast as well! I'm starting to think we should start an HN web ring for clocks.

A bit of feedback for your sun clock: since it asks for my location, by the time I clicked “Allow,” it had already timed out while trying to get the location. You may want to have it continuously check for permission changes and then initialize the sunrise and sunset features once access is granted. Cheers!
