The Data Validation method in Google Sheets lets you create a dropdown calendar in a specific cell or range of cells. This allows users to select dates from a visual calendar pop-up, ensuring precise date entry and minimizing errors.

Here’s how you can do it:
Open Google Sheets, and select ‘Blank spreadsheet.’ Give it a relevant name, like ‘Event Tracker (year) ’ or ‘Project Calendar (year).’

Next, select the cell where you want the Google Sheets calendar to appear, for example, A1.

From the main menu, go to Data > Data validation.

Next, select ‘Add rule.’

In the ‘Criteria’ dropdown, choose ‘Date is’ to allow only dates in that cell.

Under ‘Advanced options,’ check the box that says ‘Show help text for a selected cell’ to alert users if they enter incorrect data, like text instead of a date.
Finally, click ‘Done,’ and you’re all set.

You’ve successfully added a calendar to your Google Sheets document. Double-click on cell A1 to see the calendar appear.

💡Pro Tip: Another way to insert Google Sheets calendars is to simply type a date in the format yyyy-mm-dd in any cell. Double-click on that cell to make the calendar pop up immediately.
Google Sheets template gallery offers pre-designed templates that save you time by providing fully formatted online calendars. These are designed using a mix of built-in formulas and themes available in Google Sheets.
You can choose from various styles and layouts, making it simple to customize the Google calendar for personal planning, project tracking, or team schedules.
Here’s how to leverage this option:
Open Google Sheets and click ‘Template gallery’ at the top right.

Scroll through the options and select a calendar like the annual or monthly calendar template.
For example, select ‘Annual Calendar’ to open it in a new Google spreadsheet.

This Google calendar template includes both annual and monthly views, with space for notes and reminders. It allows you to:
