How to get dates from a table while the date range is from the date belonging to another table?

I have a table datedim which has all the dates of a month in it. I have another table attendance that has dates on which attendance were taken. I need to write a query where i can get all the dates from the start till current. For eg. if attendance table has records starting from 3-Apr-2019 to 3-June-2019, i should get all the dates in between them.
