Week numbers and formula

[nparsons75]

Hi, I have a table with for example 10 rows, in Col A is a name, In Col B is a formula which calculates the average of the next 52 columns. Each of the 52 columns represent a week of the year.

I would like to achieve a couple of things here. I would like a cell, maybe A1 to have the year, 2018. Based on this year, I need the row above each week number to show the month by looking at the week number below it.

Once I have this I then want to lookup and calculate the average of the values for each month.

Hope this makes some kind of sense as its difficult to explain...

Thanks in advance for any help.

	Jan	Jan	Jan	Jan	Jan	Feb	Feb	Feb	Feb
NAME	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19
name 1
name 2
name 3

Hi,

A1 formula = DATE(YEAR(TODAY()),1,1) (Gives you the first of Jan for current date)
Don't forget to format the cell to custom = yyyy

the formula for the month is ( this will give you the Monday date for each week no)
=MAX(DATE(YEAR(TODAY()),1,1),DATE(YEAR(TODAY()),1,1)-WEEKDAY(DATE(YEAR(TODAY()),1,1),2)+((RIGHT(INDIRECT(ADDRESS(ROW()+1,COLUMN())),2)-1)*7+1))

now Don't forget to format month cells to custom = mmm

This gets your dates on the first row.
