Thanks  for link but I did not get my answer could you please read my question again if you want to help me.

I asked to help me how to type 10 days based on format MM/DD? and related son/daughter whose school were closed.

Part I is an Extension of the refundable qualified sick leave.

Part II is a New family leave equivalent credit.

Also, Part II has only that one qualification. Part I is not as restrictive. They both apply between January 1, 2021, and March 31, 2021. That means the maximum of the 60 days have to fall in that 90-day window.

But April 1 to Sep 30 are included as well not fall in 90 days.
