How to generate rows from a date range

If I have a date range ( Jan 1st 2019 to Jan 12th 2019). I want to create a record foreach of dates between the 1st and the 12th. This should produce 12 records in all. If I then add another range (Jan 8th to Jan 9th), I want it to be able to generate the additional 2 rows for a total of 14 rows. 

How do I accomplish this in Power BI?
