Date and time in Google Sheets: enter, format and convert dates and time in your sheet
Today we will start discussing what can be done with dates and time in a Google spreadsheet. Let's take a closer look at how date and time can be entered into your table, and how to format and convert them to numbers.
How to insert date and time in Google Sheets
Let's start with entering date and time into a Google Sheets cell.
There are three ways to insert date and time into your Google spreadsheet:
Method #1. We add date and time manually.
It may seem to be the easiest way but locale settings that we mentioned above play a vital role here. Every country has its own pattern for displaying date and time.
As we all know, the American date format differs from the European one. If you set "United States" as your locale and type in the date in the European format, dd/mm/yyyy, it simply won't work. The entered date will be treated as a textual value. So, pay attention to that.
Method #2. Use key combinations to insert current date and time.
Place the cursor into the cell of interest and press one of the following shortcuts:
- Ctrl+; (semicolon) to enter the current date.
- Ctrl+Shift+; (semicolon) to enter the current time.
- Ctrl+Alt+Shift+; (semicolon) to add both, current date and time.
Later you'll be able to edit the values. This method helps you bypass the problem of entering incorrect date format.
Method #3. Take advantage of Google Sheets date and time functions:
TODAY() - returns the current date to a cell.
NOW() - returns the current date and time to a cell.
Here we are, we've placed date and time to our cells. The next step is to format the information to display it the way we need.
As it is with numbers, we can make our spreadsheet return date and time in various formats.
Place the cursor into the needed cell and go to Format > Number. You can choose between four different default formats or decide to create a custom one using More formats > More date and time formats:
As a result, one and the same date looks different with various formats applied:
As you can see, depending on your needs, there are a few ways to set the date format. It allows displaying any date and time value, from a day to a millisecond.
Insert time to Google Sheets in a custom number format
Suppose we need to add time in minutes and seconds: 12 minutes, 50 seconds. Place the cursor to A2, type 12:50 and press Enter on your keyboard.
What we see is Google Sheet treating our value as 12 hours 50 minutes. If we apply Duration format to A2 cell, it'll still show the time as 12:50:00.
So how can we make Google spreadsheet return only minutes and seconds?
Method #1. Type 00:12:50 to your cell.
To be honest, this may turn out a tiresome process if you need to enter multiple timestamps with minutes and seconds only.
Method #2. Type 12:50 to A2 cell and put the following formula into A3:
=A2/60
Method #3. Use special formulas.
Input minutes to A1, seconds - to B1. Enter the formula below to C1:
=TIME(0,A1,B1)
The TIME function refers to cells, takes the values and transforms them into hours (0), minutes (A1), and seconds (B1).
In order to delete excess symbols from our time, set the format again. Go to More date and time formats, and create a custom format that will show only elapsed minutes and seconds:
Convert time to decimal in Google Sheets
We move on to various operations we can do with date and time in Google Sheets.
There may be cases when you need to display time as a decimal rather than "hh:mm:ss" to perform various calculations. Why? For example, to count per-hour salary, since you can't perform any arithmetic operations using both, numbers and time.
But the problem disappears if time is decimal.
Let's say column A contains the time we started working on some task and column B shows the end time. We want to know how much time it took, and for that, in column C we use the formula below:
=B2-A2
We copy the formula down cells C3:C5 and get the result of hours and minutes. Then we transfer the values to column D using the formula:
=$C3
Then select entire column D and go to Format > Number > Number:
Unfortunately, the result we get doesn't say much at first glance. But Google Sheets has a reason for that: it displays time as a part of a 24-hour period. In other words, 50 minutes is 0.034722 of 24 hours.
Of course, this result can be used in calculations.
But since we're used to seeing time in hours, we'd like to introduce more calculations to our table. To be specific, we need to multiply the number we got by 24 (24 hours):
Now we have a decimal value, where integer and fractional reflect the number of hours. To put it simply, 50 minutes is 0.8333 hours, while 1 hour 30 minutes is 1.5 hours.
Text-formatted dates to date format with Power Tools for Google Sheets
There's one quick solution for converting dates formatted as text to a date format. It's called Power Tools. Power Tools is an add-on for Google Sheets that allows you to convert your information in a couple of clicks:
- Get the add-on for your spreadsheets from Google Sheets webstore.
- Go to Add-ons > Power Tools > Start to run the add-on and click the Convert tool icon on the add-on pane. Alternatively, you can pick the Convert tool right from the Power Tools menu.
- Select the range of cells that contain dates formatted as text.
- Check the box for the option Convert text to dates and click Convert:
Your text-formatted dates will be formatted as dates in just a few seconds.
I hope you've learned something new today. If you have any questions left, feel free to ask them in comments below.
Next time we'll continue with calculating time difference and summing dates and time together.

I created a script that lets you choose a date from a dropdown, and then auto changes the format to include time. Pasted below:
function formatColCD_ToDateTime() {
// First select columns of interest (C&D in this script) and choose
// Data → Data Validation → Criteria = Date, is valid date.
// This script then: sets the format to be date and time for the range C:D
// after a date is picked in those columns.
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName('tblInput');
var c = ss.getActiveCell();
if( c.getColumn() == 3 || c.getColumn() == 4)
{
sheet.getRange('C:D').activate();
sheet.getActiveRangeList().setNumberFormat('M/d/yyyy H:mm:ss');
}
}
Update: to paste that code click "Tools" --> "Script editor" --> paste code in. ... NOTE - you will have to change the text "tblInput" in the script to whatever your tab is named that you want the script to work on.
HELLO SAGE ,
i was trying your script code in my personal sheet , but after run process completed , it show up some error alike ""Please select an active sheet first. (line 5, file "Code")".
So my question is , how can i add active sheet in that code itself . kindly help me to solve this issue .
Hi Sage,
Below is the script you provided . . . was wondering if you could add another line of code that would set a rule to fix the time range from 8 am to 4 pm on a work day. In event the time data entered falls outside that time range, it would be default set for the next work day at 8 am. Is that possible?
Thank you in advance,
Bruce

I think this article would have solved my problem - but I didn.t stop toread it. The moving bar across the bottom is too distracting.
This is worse than auto-play videos - at least you can mute those.
Thank you for your feedback, Flip.
You can make the bar much smaller by clicking on the corresponding button at its upper right corner.
I will pass your feedback to our team so they could take it into account.
Hello, talking about time... I'm new to sheets, coming from excel and still adapting to things I thought were basic and sheets doesnt' do.
I'm trying to write the time manually in a cell, wich by the way is formatted appropriately, and I have to write 8:00 or 8:01, in excel I could just type 8: or 8:1 and because the cell is time formatted it would understand it. Is there a way to do this in sheets or quicker way to manually write time?
Hello Emanuel,
If you enter simply 8:1, Google won't recognize it since it can be 8:10 as well as 8:01. Thus, I'm afraid in Google Sheets you should indicate the time in a way so spreadsheet understands it correctly: with two digits after the colon. This way the time format will be applied automatically.
Is there a way to change the value of the column to subtract 2 hours from the time entered? Say I enter 15:00 can I have it show 13:00 instead?
Henry,
in one and the same cell - no.
You'll need a formula to subtract 2 hours from your time. For example, you can enter the time to A2 and put the formula below to B2:
=A2-TIME(2,0,0)
Whatever time you enter to A2, B2 will always subtract two hours from it and will show you the result.
