What cell do you want "Feb" to be in
I assume the text and the month are to go up to only today
Try this and tell me if it is close
In A1:B1 type "Jan" and "Feb"; drag along to L1 to get all the months
Select A1:L1 and use conditional formatting Formula Is
=COLUMN(A1)>MONTH(TODAY())
and set the font colour the same as worksheet background (white?) to make
future months invisible
In A2 enter
=IF(COLUMN(A1)=MONTH(TODAY()),TODAY(),IF(COLUMN(A1)>MONTH(TODAY()),"",DATE(YEAR(TODAY()),COLUMN(A1)+1,0)))
drag this to L2
Now you will see
Jan Feb Mar Apr May Jun Jul
31 28 31 30 31 30 07
If this is close to what you want, we need to adjust things if your timeline
starts in a column other than A
