This demonstration company has been set up on a fiscal year basis with the fiscal (accounting) year starting in April so that the last month of their year is March. If you keep your books on a calendar year basis you would set the ending month to December. If you use a fiscal year set the ending month to the last month of the fiscal year, i.e., the month before your fiscal year begins.
