Why is the week count number in my report appear to be "off" by one week?
Oracle B2C Service, All versions
The product counts weeks starting with Sunday, ending with Saturday. This means that week #1 in the product will be the week with the first Sunday in January (not always January 1st).
Other sources may count the week with January 1st as week #1. This is why the week count in the report may not match the expected week count.
