I have a question. In my progress snapshot, there are 9 choices of time span, namely Today Yesterday Last 7 days Last 2 weeks Last month Last 3 months Last 6 months Last year All time. When I hear "last year" on 26th Dec. 2013, I assume it refers to the year of 2012. However, I think "last year" here means the time span from 27th Dec. 2012 to 26th Dec. 2013. I'm a little confused about the definition of "last year". Why don't you say "last one year" instead of "last year" ? And then when does "this year"represent ?
