Copy range of 28 cells and paste to duplicate every 28 cells

I am hoping this is easy and I am just over looking something. I am making a work schedule with cell a2 being the first day of the year and cell A366 being the last day of the year. I simply want to enter a schedule for a number of days (i.e. 28 days cells a2-a29) and duplicate them every 28 days without having to cut and paste every 28 day schedule. I hope this makes sense. I appreciate any help that is available.

This probably isn't the right thread for this but I would also like to have the opportunity to enter a number of days to carry the out to. For example if I only wanted to carry the schedule out 240 days with that schedule duplicating every 28 days it would be nice to manipulate how many days I can carry out the schedule.

Put this formula in B30 after setting up the values in B2 to B29:

=B2

Then just copy this down to cell B366.

Hope this helps.
