Tips While Using

2. Type the DAY formula directly in a cell
Entry path: Cell → Formula bar
- Select the cell where you want to enter the formula.
- Type
=DAY(...)directly in the cell or in the formula bar. - Replace the argument inside the parentheses with a date cell, a date value, or a formula that returns a date.
- Press Enter to confirm.
- If you want to use it in multiple cells, drag the fill handle to copy the formula.
Success Criteria
- Interface result: The cell returns an integer from 1 to 31.
- Next action available: You can copy the formula, adjust references, or combine it with other functions.
Tips While Using
- Common mistake: If the argument is not a valid date, the result may return an error or an unexpected value.
- Environment note: When entering a literal date directly, use a date format that the current worksheet can recognize.
3. Check the DAY syntax and parameter details
Entry path: Formula tab → Insert Function
- Click Insert Function on the Formula tab.
- Type DAY in the search box.
- Select the function and review the syntax
DAY(serial_number). - Read the parameter description to confirm what kind of date value is required.
- If a help entry is available in the interface, open it for more details.
Success Criteria
- Interface result: You can see the DAY function name, syntax, and parameter description.
- Next action available: You can return to the worksheet and enter the formula with the correct argument.
Tips While Using
- Common mistake: Checking only the function name without confirming the parameter type can lead to input errors.
- Environment note: Different date input styles may be interpreted differently in the worksheet, so using a date cell reference is usually more stable.
