Show HN: Minimal and clean ordinal date utility

I need the 'julian date' frequently at work, and got tired of searching a table, or clicking through a site filled with lots of other 'stuff' looking for it, so I created this instead.

My intent was to make it as single-focused, clean, and fast as possible. Clicking on the day number allows you to type in another to get the date for that ordinal date.

Feedback/criticism welcome!
