12 mtd goes back 12 months, whereas a ytd is from the first day of the current year (calendar, fiscal, whatever) to the current day.

REPORT TYPE - REPORT PERIOD

---

12MTD report - 20080401 to 20090318

YTD report - 20090101 to 20090318

Answer 3

In addition to Hank Gay's answer, a 12 mtd calculation is the same as a 12 mtd rolling calculation.

General, you would normally see a 3 mtd rolling, or 6 mtd rolling calcuations.
