Possible to change Traffic Manager start/end dates?

[happydish]

Pretty much the title question. For the traffic analyzer you can monitor the monthly data usage. My cable company doesn't measure my data cap by month. Instead its the 14th to the 14th (Weird I know). Is it possible to change the start/end dates for the monthly traffic manager? I'm currently on firmware 380.66_4 on a RT-AC68U.
Thanks!

Yeah, click on the Tools tab, Other Settings and change the "Starting day of monthly cycle"

Note: if you change to the 15th (if the period ends on the 14th) today, it would keep adding onto August until September 14th and then start counting September's month on September 15th. So, you would have one month with some extra days.

It doesn't change the start/end dates for previous months.

At least, that's what happened to me when I changed it from the 1st to the 15th.
