Short version of this request: Add 366 as an option in "days minus" of date manager.
Why? If you want to build a YTD comparison for last year and this year, you are forced to include "today" a year ago -- which will be a full 24 hours -- and "today" this year, which may be far less than a full day. Ideally, I would want a YTD that excludes "today" which is easy to build for the current year, but impossible for the previous year.
Model now for LAST Year-to-date:
Setting this rolling timeframe on Aug. 17, 2016
-Start of- -current year- -minus- -1- -year -
-Start of- - current day- -minus- -365- -days
Which gets me 1/1/15-8/17/15
If I could set minus-days to 366 I could get to the desired rolling window of 1/1/15-8/16/15
