Komga doesn't accept dates lower than 1000

[Eskuero]

Steps to reproduce

1. Try to change the publication date of a book via webui to year 999
2. Additionally even if the dates were parsed, the webui date selector doesn't go into BC

Expected behavior

Writting was invented 5000 years ago. In fact I discovered this error because I added the "Epic of Gilgamesh" to my library and I was trying to set the correct date. The epub date was set to year 2500. Setting it to -2500 made Komga show it still as year 2500 for publication.

I don't know whether epub definition allows negative dates but imho Komga should allow the modification to the imported metadata via the webui.

Actual behavior

The webui shows a error and nothing changes.

From what I see HTML won't support BCE dates so I guess negatives would be a pain, still less 1000 would be nice

i doubt you would have books published before year 1000 though, no?

You need to make sure the leading zeros are present:
