Release date formats are also not only US centric but also incoherent across all site, for example under "editions" tab books have YYYY-MM-DD but when editing you have to fill MM-DD-YYYY.

Actually I live in the US and sometimes my read dates still end up wrong, depending on what time of day I update my reading. They are aware of this thanks to conversations on Discord and will hopefully get user time zones set up at some point, though I don't think it's high on the priorities right now
