Move Data

I am working in vb6. Or should i say i am trying to work in vb6. I think a self taught person with only the help file don’t stand a chance.

I am trying to move data from one textbox to another and it must only move on the first day of the month.
These are my boxes.

Text21(0)----each of these represent one month
text21(1)----i need the data to move down
text21(2)----for instance text21(0) data moves to
text21(3)----text21(1) and so on down the line
text21(4)----but it must move only on first day of month
text21(5)----i have no idea how to start this
text21(6)----i have no code to start
text21(7)
text21(8)
text21(9)
text21(10)
text21(11)

i really thank you for the help.
