"Previous Period" is based strictly on the number of days in the requested Range the number of comparison days will always match 1:1 with the Range days.
|example: Range =||Last 7 days|
|Comparison =||Previous Period|
|Result =||The Previous 7 Days will be compared|
"Previous Calendar Period" is based on the number of days in a calendar Range.
|example: Range =||Last Month|
|Comparison =||Previous Calendar Period|
|Result =||The Previous Month will be compared|
Previous Calendar Period should be selected when comparing month to month due to the different number of days in a given month vs another month.
- example: Feb 1 - 28 vs. Jan 1 - 30
Note: If Previous Period is used for Month-to-Month comparisons then we would loose 2 days from January
