Hints to get you started
- Excel stores dates as numbers.
- DATE takes year, month, and day in that order.
- Reference B2, C2, and D2 instead of typing their values.
Show the worked solution
=DATE(B2,C2,D2)DATE constructs a date from separate fields. Cellcraft uses Excel’s 1900 date system; in Excel, apply a Date format to display the serial as a calendar date.
Make the skill stick
After solving the task, explain what each reference does and why the formula answers the business question. Try the workbook download inside the quest to practice in your own spreadsheet app.
