Usage: Ending date and time of the Time Period. End Date is not required if Start Date is present.Pick a Fiscal Year Use this select control to set both the Start Date and End Date of a fiscal year. To set both dates for a fiscal year use the control to select the desired starting year. The Start Date will be set to the first day of the month for the fiscal year and the End Date will be the last day of the month twelve months later. The default starting month for the fiscal year is October. The starting month can be changed on the Settings page and will used by mdEditor for all Time Period objects until changed. Previously defined fiscal years will not be effected.
