How do a set the current date to change in cell everyday

[erie2446]

I have a created a spreadsheet that calulates the number of days between two
dates. Since I have 30 entries to track I must change the current date in 30
cells. However, I have to manually change the current date in 30 cells. Is
there a formula to automatically change the current day in the cells?

in the cells that have to have the current date use =Now()

or

place =Now() in a single cell (e.g., A1) and have the cells that have the
current date point to that cell =A1
