Number of days passed monthly/yearly

I would like to use a formula that calculates the number of days passed in month based on the current date.
I have todays date, and i know how many working days are in the month but I would like the formula to calculate how many days have passed based on the todays date.
Can this also apply for yearly and what formula would i use?

Attached is sample of what i am trying to do.

Try this formula in B3

=NETWORKDAYS(B1-DAY(B1)+1,B1,J2:J11)

and in B5

=NETWORKDAYS(DATE(YEAR(B1),1,1),B1,J2:J11)

Those will both include today's date in the count......
