How To Autofill Dates In Excel

Productivity Software

Let me show you how to save time and effort by autofilling dates in Excel. As a data enthusiast, I often find myself needing to generate a series of dates in Excel for various analyses and reports. Instead of manually typing out each date, Excel’s autofill feature can streamline this process. I’ll walk you through the steps to efficiently autofill dates based on your specific needs.

Autofilling Dates in Excel

First, select the cell where you want the series of dates to start. Then, enter the initial date, for example, “1/1/2022”.

Next, hover over the bottom-right corner of the cell until you see the black cross symbol. Double click on this, and Excel will automatically populate the following cells with a sequence of dates based on your initial date.

Customizing the Date Sequence

If you want to customize the sequence of dates, you can use Excel’s fill handle to extend the date series in different patterns. For example, if you want to skip days and create a series of every other day or every third day, simply adjust the initial two dates and then use the fill handle to autofill the pattern.

Using the Fill Series Feature

If you have a specific pattern in mind, such as every Monday, Wednesday, and Friday, you can use the “Fill Series” feature. After entering the first few dates that follow your pattern, select these cells and then go to the “Fill” option under the “Editing” group on the Home tab. Choose “Series” and customize the settings to fit your desired date sequence.

Adding a Date Increment

If you want to create a sequence with a specific increment, such as adding one month to each date, you can use the EDATE function. In a new cell, enter the formula “=EDATE(start_date, months)” where “start_date” is the reference to your initial date and “months” is the number of months to add. Drag the fill handle to extend the series with the incremented dates.


Mastering the art of autofilling dates in Excel can significantly enhance your productivity when working with date-based data. Whether it’s for scheduling, financial modeling, or any other application, this skill is invaluable. By leveraging Excel’s autofill and fill series features, you can effortlessly generate date sequences that fit your specific requirements.
