Final answer:
Dillman Pickle's first fiscal year begins on its incorporation date, July 2, 20Y5, and ends on December 31, 20Y5, constituting a short fiscal year.
Step-by-step explanation:
The question asks when the first fiscal year occurs for Dillman Pickle after it incorporates on July 2, 20Y5, with the adoption of a calendar year-end. Dillman Pickle's first fiscal year would typically start on the date of incorporation and end on December 31 of that year, making the first fiscal year a short year if it's less than 12 months. Since the company incorporates on July 2, 20Y5 and adopts a calendar year-end, the first fiscal year for Dillman Pickle would be from July 2, 20Y5, to December 31, 20Y5.
