365 days at 6 columns per day gives you in excess of 2000 columns which is
nearly 10 times the maximum number of columns you can have (256 is the max).
You will need to consider transposing your data, albeit timelines don't
always work nicely when vertical.

I am trying to make a timeline for all of 2005, Jan-Dec. I also need to
include 6 colums of -data related to each day on the timeline. I now have
to
worksheet dividing the year in-half, with some overflow added to each
section, Jan-Aug & Jun-Dec.

Can I get all of this on one worksheet?
