My employer is not on a calendar year fiscal cycle. Instead, its fiscal starts May 1.
As a result Q1 is May-June-July, Q2 is August-September-October, etc.
Act assumes the "current quarter" in the opportunities and reporting sections are calendar quarters. It is a nuisance to have to readjust everything for my employers fiscal. I know other companies, and the US Government, are on non-calendar cycles.
If the definition of when the fiscal year starts can be user defined that would be quite valuable.
