I wish there was a way (either through the admin tool or by working with
an Omni consultant) to customize the calendar months / years to suit any
situation. For example, our business works in "marketing periods"
instead of months. There are 13 marketing periods in a year, each
containing 4 weeks (except every few years, the 13th period has 5 weeks
from the carryover). Additionally, the fiscal weeks run from Thur - Wed.
None of the custom calendar options suit the needs of my business.
