Entering dates in Excel


Excel is a powerful tool for managing and analyzing data, including dates. This tutorial will cover the various methods of entering dates in Excel, from manually inputting them to using shortcuts and importing dates from other sources.

A. Manually inputting dates
  • Typing in the date


    To manually input a date in Excel, simply click on the cell where you want the date to appear and type it in using the correct format (e.g. "mm/dd/yyyy" or "dd/mm/yyyy").

  • Using the date picker


    If you prefer a more visual approach, you can use the date picker tool in Excel to select a date from a calendar and have it automatically entered into the cell.


B. Using shortcuts to enter dates
  • Auto-fill


    Excel has a built-in feature that allows you to quickly enter a series of dates by typing in the first date, selecting the cell, and dragging the fill handle down the column to automatically fill in the subsequent dates.

  • Keyboard shortcuts


    There are also keyboard shortcuts you can use to enter the current date or time into a cell, such as "Ctrl + ;" for the current date and "Ctrl + Shift + ;" for the current time.


C. Importing dates from other sources
  • From a CSV or text file


    If you have dates stored in a CSV or text file, you can easily import them into Excel by using the "Get External Data" feature and following the prompts to select and import the dates.

  • From a database or web source


    Excel also allows you to connect to external data sources, such as a database or a web page, and import dates directly into your spreadsheet.



Performing calculations with dates


When working with dates in Excel, it's important to know how to perform calculations with them. Whether it's adding or subtracting dates, calculating the difference between two dates, or using dates in formulas, Excel provides various functions to handle date calculations efficiently.

Adding and subtracting dates


  • To add a specific number of days to a date, use the DATE function along with the YEAR, MONTH, and DAY functions to specify the new date.
  • To subtract a specific number of days from a date, use the same approach with negative values for the days.
  • For example, to add 5 days to a date in cell A1, use the formula =A1+5.

Calculating the difference between two dates


  • To calculate the difference between two dates, simply subtract the earlier date from the later date.
  • Excel will return the difference in days as a numeric value.
  • For example, to calculate the difference between the dates in cells A1 and B1, use the formula =B1-A1.

Using dates in formulas


  • Dates can be used in various formulas just like any other numeric values in Excel.
  • For example, to count the number of days between two dates, use the DATEDIF function.
  • Similarly, dates can be used in conditional formatting, pivot tables, and other data analysis tools in Excel.
