Converting Numbers to Dates in Excel

Using Formulas to Convert Numbers to Dates

To convert a number to a date in Excel, use the formula =DATE(1900, 1, 1) + A1 - 2. This formula leverages the DATE function to create an Excel date based on the serial number in cell A1. Excel recognizes January 1, 1900, as serial number 2, hence the subtraction of 2. The addition operator combines the adjusted serial number with the base date to yield the correct date value.

Formatting Cells for Date Conversion

Excel's cell format plays a crucial role in how numbers are displayed as dates. You can convert a number to a date by changing the cell format. Access the Number Format drop-down or the Date format option to apply a pre-defined date format. Alternatively, use the Custom Date Format for more control over the display.

Using Text and Date Functions

For text strings resembling dates, the TEXT function can format them as date values. Use the DATEVALUE function to turn text into a serial number that Excel interprets as a date. The VALUE function offers a broader functionality, converting any text that looks like a date into a numeric form. For complex date strings, functions like TEXTSPLIT, MID, LEFT, and RIGHT can parse the string into components, which you then reassemble with the DATE function to achieve the desired format.

Utilizing Excel's DATE Function

The DATE function can be employed to convert numbers to dates. Given a text string, such as "Sep 26, 1989", parse it with text functions and then use the DATE function to reformat it into "MM/DD/YYYY". Excel's local settings will determine the exact format used.
