How to convert a string (43677) to date in SQL(Redshift)? (I'm trying to convert strings, which are number format of any particular date in excel)

It depends what day you want, but I think:
select dateadd(day, 43677, '1899-12-30')
This interprets the value as an Excel date. It produce 2019-07-31.

I want to find if the difference between 2 columns. How do I achieve that?
For example,
