2. Right-click to open the context menu and select Format Cells.

Using Custom Date Formats

Using Pre-Defined Date Formats

1. In the Format Cells dialog, go to the Number tab.
2. Select Date in the Category list.

   • dd-mmm-yy for 31-Dec-23
   • mmmm dd, yyyy for December 31, 2023

Using Date Functions

Extracting Parts of a Date

1. YEAR Function: =YEAR(A1) – Extracts the year from the date in cell A1.
2. MONTH Function: =MONTH(A1) – Extracts the month from the date in cell A1.
3. DAY Function: =DAY(A1) – Extracts the day from the date in cell A1.

Combining Dates

1. DATE Function: =DATE(year, month, day)\nExample: =DATE(2023, 12, 31) results in 12/31/2023.

Formatting as Text

1. TEXT Function: =TEXT(A1, "dd/mm/yyyy") – Formats the date in A1 as 31/12/2023.

Converting Text to Date

1. Use the DATEVALUE Function: =DATEVALUE("31/12/2023")\nConverts the text "31/12/2023" to a date value.

Inserting the Current Date and Time

1. Current Date: =TODAY()\nInserts the current date.
2. Current Date and Time: =NOW()\nInserts the current date and time.

Using Date Formatting in Charts

' Select the cells you're working with
Range("A1:A10").Select

' Open Format Cells Dialog
With Selection
    Selection.NumberFormat = "$#,##0.00"
