Summary

st.date_input widget is unable to go before January 2000, e.g. 1999,1990, etc… It doesn’t matter if you use the dropdown box or the left arrow, because when it arrives in January 2000 the left arrow disappears.

Steps to reproduce

1. Put a st.date_input in your app
2. Try using arrows/or scroll in the dropdown menu before date: January 2000

You can actually set a date before January 2000 if you initialize it using value parameter, e.g.
d = st.date_input('When's your birthday', datetime.date(1980, 7, 6))
But even in this case, you don't see the left arrow anymore only the right one, also the dropdown still only shows Januar 2000.

Expected behavior:

Use the arrows or scroll through the dropdown box to go at any date in the past (or at least till 1900).

Actual behavior:

As soon as you reach at January, 2000 the left arrow disappears and also the scroll ends.

Is this a regression?

I don't know, because I haven't used it in the past.
