Description

Error:

RECV: {"method":"update","data":{"x:shiny.date":"900-02-09"}}
_send_error_response: time data '900-02-09' does not match format '%Y-%m-%d'

Ideally, it would be great to have BC dates as well (year<0).

Contributor guide

Research direction
Investigate the ui.input date() implementation to find the date parsing logic and modify it to support years outside the range 1000-9999, including negative years for BC dates.
