Hi,

I'm looking to update calendar in Adobe Analytics to run from Mon - Sun (rather than the defulat Sun-Sat), however, when doing this (and when reading documentation) there is a warning that states:

"When a calendar’s definition of weeks and months changes, historical data is not altered." 

I'm not fully sure what this means, does this mean that any data (i.e. Visits, Unique Vistors) prior to the change will still be calculated on a Sun-Sat basis? I've made the change in a Dev report suite and the data appears to update/backdate as expected.

Am I missing an unexpected draw backs/discrepancies that may occur or will making this change simply update how "weekly" data is viewed in Analytics, as I expected, and work historically?

Thanks

Toby
