07/19/2023, 8:36 PMThe classical way for sparse date is to create those missing dates and fill them with 0s given that on those date nothing happened.

07/19/2023, 8:37 PMInstead of:
Date 1: 234
Date 5: 7787
you would have:
Date 1: 234
Date 2: 0
Date 3: 0
Date 4: 0
Date 5: 7787

07/20/2023, 5:18 PMYes, it will. But for the better, assuming that missing data indeed signifies 0.
This is often the case in retail data: stores don't usually report 0 sales for items or SKUs. If something doesn't sell, they simply omit that information.
