In order to craft dateDefaultValue above we do something a bit different. We should align whatever we choose here with that.

1. new Date().toISOString().substring(0, 10)
   • This does not work when the year is 99000: (new Date('99000-05-05').toISOString().substring(0, 10) -> '+099000-05')
   • This also feels ripe for the same problem that user-agent parsers had when Chrome went from 99 to 100
2. new Date().toISOString().split('T')[0]
   • This does better when the year is 99000 but it's not in the format that the date <input> wants: new Date('99000-05-05').toISOString().split('T')[0] -> '+099000-05-05'

Those options are considerably simpler than the current code but this always does the right thing. We probably just need to package this logic up into a function at the top called formatDateForInput and re-use it in both places.

    const date = new Date(ts);
    const year = date.getFullYear();
    const month = `${date.getMonth() + 1}`.padStart(2, "0");
    const day = `${date.getDate()}`.padStart(2, "0");
    const dateDefaultValue = `${year}-${month}-${day}`;

@aman-godara Is this PR meant to be in draft? Draft means you're still working on it and it's not ready for review yet.

I was trying to test this on my local machine, hence I keep it under draft. The coding part is done unless testing fails.
