Color code alternate rows based on date in google sheets

Question

I would like to shade the rows based on alternate dates in google sheets. For example, the first row will always be unshaded, following that in the picture below, there is a new date "2021-03-19" in rows 2 and 3, hence they need to be shaded. Following that, next date, 2021-01-01 does not need to be and so on.

I have recently started using google sheets, not sure whether it can be achieved using any in built command.

Any suggestions would be appreciated.
