# working formula for =SUM(H37/"current day (19)" * days in the month (this month has 31)

I can do the basic formula =SUM(H37/19*31) [what the formula is today] but i don't know how to make it automatic with the current day and month.

What do you expect the formula

`=SUM(H37/DAY(TODAY))*DAYSINMONTH(TODAY()))`

to achieve? What is the call to the SUM() function supposed to be useful for? In other words: Why not simply`=H37/DAY(TODAY))*DAYSINMONTH(TODAY())`

?Isn't there any cell in the sheet already providing the result of TODAY()? Would make the formula more simple and clear. Probably use a spare cell for this and reference it in the formula.
