Show HN: Sunrise Calendar: custom printed calendar with sun and moon info

This is a personal project that I've been working on very slowly now on the side for the past 4 years (yes, ridiculously long), using it for myself for a while and now finally have it ready to share to a wider audience.

It's a web app for building printed wall calendars that include sun and moon info for each day, specific to the location you choose. Rather than using accounts, each calendar gets its own unique URL by which it can be accessed. This way there are no accounts, no logging in, no tracking, etc. Everything is deleted 7 days after the last access, or if ordered, 18 months after the last access. There's no email list, no collecting/saving of email, etc. It's for creating and printing calendars; nothing else.

I built it with nodejs and pdfkit for creating the calendar PDF that gets sent to the printer (lulu.com). I'm just using file storage of json documents to start with -- I know this is not ideal, but I started simple and lightweight and will fix things if/when needed. In the past I've been overly obsessed with using all the right tools and everything, but that can sometimes distract from the simple core goal, so for this I've intentionally taken a different approach (specifically since this is more of a "just for fun" project).

Thanks for checking it out! If you order in the next couple days, it should still arrive before Christmas in the US. (As long as not too many order all at once!)
