Moment.js Fiscal Year Calculations (FY starts in October)

moment.fiscal_year.js

if (moment().quarter() == 4) {
  var current_fiscal_year_start = moment().month('October').startOf('month');
  var current_fiscal_year_end = moment().add('year', 1).month('September').endOf('month');                  
  var last_fiscal_year_start = moment().subtract('year', 1).month('October').startOf('month');
  var last_fiscal_year_end = moment().month('September').endOf('month');
} else {
  var current_fiscal_year_start = moment().subtract('year', 1).month('October').startOf('month');
  var current_fiscal_year_end = moment().month('September').endOf('month');                   
  var last_fiscal_year_start = moment().subtract('year', 2).month('October').startOf('month');
  var last_fiscal_year_end = moment().subtract('year', 1).month('September').endOf('month');
};
