How to add dates manually in Google Sheets

Sometimes, when you’re working on simple spreadsheets, manual entry is efficient, fast, flexible, and perfect for fixed dates. You can add dates to your Google Sheet spreadsheet with just number formatting.

1. How to add date to spreadsheet with number formatting

This is probably the easiest method to insert dates in spreadsheets. Google Sheets basically treats dates like numbers, with proper formatting you can present numbers like dates.

1. Select the cells or column for dates.
2. Go to Format, Number, Date for a standard format.
3. For a custom look, pick Format, Number, Custom date and time.
4. Type in dates like 1/5/2025 or 2025-01-05. Sheets will convert number and display it as dates.

What to look for if your date is not displayed properly

• Set your file Locale in File -> Settings to match your audience’s region.
• If a date shows left-aligned, it is probably text. Remove any leading apostrophe.
• Keep date columns consistent. Mix of text and dates breaks sorting and formulas.

What are some common date formats you can use in your spreadsheets?

Your buyers might read dates differently. Use formats that feel obvious to them and reduce support questions.

Some common formats to style number as a date are:

• Short date for compact tables, like 1/5/2025.
• Long date for readable schedules, like Sunday, January 5, 2025.
• With time: use this in places where accurate time stamping is needed, like Jan 5, 2025 2:07 PM

Example: Enter 1/5/2025 in A2, then apply mmmm d, yyyy to display January 5, 2025 without changing the underlying value. It will display your date in selected format.

How to Add Dates in Google Sheets Automatically with Formulas

While inserting dates manually is good enough for simple spreadsheets, most require more complex needs.

In these cases, you can insert dates automatically to save time, educe errors, and keep templates updated for changing dates.

1. TODAY and NOW Functions for Real-Time Updates

Use these two functions when you want live dates.

• =TODAY() inserts the current date.
• =NOW() inserts the current date and time.

Step-by-step setup:

1. Click a cell where you want to insert today’s date
2. Type =TODAY() and press Enter.
3. Format the cell as a date in Format, Number, Date.
4. If you want to insert date + time, Use =NOW() , then format as Date time.

Where to use these methods:

• Dashboards: show “Updated on” with =TODAY() so buyers know the sheet is fresh.
• Creation date: place =TODAY() in a hidden setup sheet, then pull that cell into headers.
• Schedules: base rolling views on =TODAY() to highlight tasks due this week.

Limitation to keep in mind when using Today() or Now() methods:

TODAY and NOW recalculate when the file opens or when you edit. If you don’t want the date to change, then you must freeze it. Otherwise it will change to current Date or time.

2. How to create a rolling list of dates:

You can create a dynamic list of dates for any number of days by using the following formula:

Insert below formula in the starting cell:

=SEQUENCE(7,1,TODAY(),1) 

It will insert date in the below cells, you can format the subsequent cells as Date format for proper display.
