Used tile tool with the equal records method. Used 2 as number of tiles so i'd have 2 separate sequences of 1-12 for each month. This also gave me 2 tile numbers, 1 if it was in 2007 and 2 if it was in 2008. Then used a formula to replace each number with its corresponding month (i.e. 1 is Jan, 2 is Feb, etc.). Pulled in another formula to combine 0 with the tile number plus 6, which came out to "07" in 2007 and "08" in 2008. Finally a select tool to match output.
