What you will practise
DATE returns a numeric date serial. The worksheet displays date cells as YYYY-MM-DD using Excel's 1900 system. Month 13 moves to next January; day zero is the final day of the preceding month. Use numeric components, not localized date text.
DATE(year, month, day)The syntax above is a guide. Read the data and each task to choose the right arguments for your formula.
3 exercises in this lesson
- Exercise 1 · answer in E10
Build the deadline from year B2, month C2 and day D2.
- Exercise 2 · answer in E10
Build the first day of the month after the period in B3 and C3.
- Exercise 3 · answer in E10
Find the last day of the month in B4 and C4: use day zero of the following month.
Before you check your answer
- Keep the source data intact. Write your answer in the highlighted result cell. Changing a source value changes the question instead of solving it.
- Use the requested cells. Check the first and last row of a range and read its column heading. A plausible total can still come from the wrong data.
- Reference values that can change. A fixed number may match today's sheet. A cell reference keeps the formula connected when the source values change.
How the answer is checked
The workbook evaluates your formula against the requested result. It also checks the skill being practised and tests the formula with changed source data, so a fixed answer that happens to match is not enough.
Use progressive hints when you need help, then try the task again with fresh data. Correctly solving a step opens the next exercise.
The workbook opens with this skill selected. Work through the exercises at your own pace.
