Today, let’s travel in time. Pack your photon ray guns, extra underwear, buckle your seat belts and open Excel!
Of course, we are not going to travel in time. (Come to think of it, we are going to travel in time. By the time you finish reading this, you would have traveled a few minutes)
We are going to learn how to travel in time when using Excel. In simple terms, you are going to learn how to move forward or backward in time using Excel formulas.
So are you ready to hit the warp speed? Let’s beam up our Excel time machine.
Tip 0 – Date & Time are an illusion
Most important tip for Excel time travelers is to understand that Excel dates & times are just numbers. So when you see a date like 17-October-2013 in a cell, you can safely assume that it is a number disguised to look like 17th of October, 2013. To see the number behind this, just select the cell and format it as number (from Home ribbon).
Now that you understood this concept, let’s jump in to the 42 tips. All these tips assume a date or time value is in the cell A1.
Staying at present:
- To have latest star date in a cell, just press CTRL+; (of course, in Excel world, star date is nothing but whatever date your computer shows)
- To have current time in a cell, just press CTRL+:
- Of course, we time travelers are lazy. So pressing CTRL+; every day or CTRL+: every second is not cool. That is why you can use =TODAY() in a cell to get today’s date. It will automatically change when you re-open the file tomorrow.
- Likewise, use =NOW() to get current date & time in a cell. Remember, although time changes every second, you will not see the cell updated unless the formula is somehow re-calculated. This is done by,
- Pressing F9
- Saving / re-opening the file
- Making any changes to any cell (like typing a value, changing a value)
- Editing the formula cell and pressing Enter
- To check if today is after or before the date in cell A1, you can use =TODAY() > A1. This will be TRUE if A1 has a past date and FALSE if A1 has a future date.
- To know how many days are there between TODAY and the date in A1, use =TODAY() – A1. This will be a negative number if A1 is a future date. To see just the number of days (without negative sign), you can use =ABS(TODAY()-A1)
- To know how many hours are left between the time in A1 and current time, use =(NOW()-A1)*24.
- While the above formula works, it shows hours and fraction. To just see hours and minutes left, you can use =TEXT((NOW()-A1), “[hh]:mm”). Note: This formula works only when A1 < NOW().
- To know how many weeks are left between TODAY() date and a future date in A1, use =(TODAY() –
A1)/7 - To know how many months are left between TODAY() and date in A1, use = DATEDIF(TODAY(), A1, “m”).
Related: How to use DATEDIF function. - To know which month is running, use =MONTH(TODAY())
- To see the month name instead of number, use =TEXT(TODAY(), “MMMM”). This shows the month’s name in your Excel language.
- To know which year is running, use =YEAR(TODAY())
- To see the last 2 digits of the year, you can use =RIGHT(YEAR(TODAY()), 2)
- To find the day of week for TODAY, use =WEEKDAY(TODAY()). This will give a number (1 to 7, 1 for Sunday, 7 for Saturday).
- To see the weekday name instead of number, use =TEXT(TODAY(), “DDDD”).
- To see today’s date alone, use =DAY(TODAY())
- To know if the present year is a leap year or not, see this.
Going back in time
- To go back by 6 days from the date in A1, use =A1-6
- To go back to last Friday use =A1-WEEKDAY(A1, 16). This works in Excel 2010, 2013. If your time machine is old (ie you have Excel 2003 or earlier versions), you can use =A1-CHOOSE(WEEKDAY(A1), 2,3,4,5,6,7,1)
- To go back by 5 weeks, use =A1-5*7
- To go back to start of the month, use =DATE(YEAR(A1), MONTH(A1),1)
- To go back to end of previous month, use = DATE(YEAR(A1), MONTH(A1),1) – 1
- Or use =EOMONTH(A1,-1)
- To go back by 2 months, use =EDATE(A1, -2)
- To go back by 27 working days, use =WORKDAY(A1, -27). This assumes, Monday to Friday as working days.
- To go back by 27 working days, assuming you follow Monday to Friday work week and a set of extra holidays, use =WORKDAY(A1, -27, LIST_OF_HOLIDAYS)
- To go back by 7 quarters, use =EDATE(A1, -7 * 3)
- To go back to the start of the year, =DATE(YEAR(A1), 1,1)
- To go back to same date last year, = DATE(YEAR(A1)-1, MONTH(A1), DAY(A1))
- To go back a decade, =DATE(YEAR(A1)-10, MONTH(A1), DAY(A1))
Going forward in time
We, time travelers are smart people. Once you know that turning the knob backwards takes you to past, you know how to go to future. So I am giving very few examples for going forward in time.
- To go to the 17th working day from date A1, assuming you use Sunday to Thursday workweek, use =WORKDAY.INTL(A1,17,7). This formula works in Excel 2010 or above.
- To go to next hour, use=A1+1/24
- To go to next day morning 9AM, use =INT(A1+1) + 9/24
- To go to 18th of next month, use =DATE(YEAR(A1), MONTH(A1)+1, 18)
- To go to end of the current quarter for date in A1, use =DATE(YEAR(A1), CHOOSE(MONTH(A1), 4,4,4,7,7,7,10,10,10,13,13,13),1)-1
- To go to a future date that is 4 years, 6 months, 7 days away from A1, use =DATE(YEAR(A1)+4, MONTH(A1)+6, DAY(A1)+7)
Finding the amount of time traveled
- To know how many days are between 2 dates (in A1 & A2), use =A1-A2
- To know how many working days are between 2 dates, use =NETWORKDAYS(A1, A2) (remember: A1 should be less than A2).
Fixes for common time travel hiccups
- If you see ###### instead of a date in a cell, try making the column wider. If you still see ######, that means the date value is not understandable by Excel (negative numbers, dates prior to 1st of January 1900 etc.)
- Often when pasting date values in to Excel, you notice that they are not treated as dates. Use these techniques to fix.
- If you pass in-correct values or use wrong parameters, your date formulas show an error like #NUM or #VALUE. Read this to understand how to fix such errors.
Quiz time for time travelers
I see that you safely made it here. I hope you had a good journey. Let me see how good your time traveling is. Answer these questions:
- Write a formula to take date in A1 to next month’s first Monday.
- Given a date in A1, find out the closest Christmas date to it.

This borders on Excel soft-cell...er, soft-core...porn. My favorite kind.
Wow, that is pimp-TASTIC! I have a question, as a VBA n00b: additional comment boxes stay plain unless I "run" the macro. Is there a way to change all comments, going-forward?
hi Chandoo, well, I like the macro approach. For those who don't like it, there is another way: just add the "draw" toolbar to the shapes toolbar (via Custom etc), click on "edit comment", click on the auto-shape and then choose "draw" drop-down, --> modify auto-shape --> then you even can have a heart or a banner (I like the horizontal banner in in purple :-)) . in excel 2007, you have to add this custom menu that you choose via Excel Options --> Custom --> it is called "change/ modify auto-shape"!!!
best,
@Chandoo. Great Post 🙂
@Tim : the way the macro is coded, it must be run very time.
@Community: If someone has an idea to perform it when opening an existing excel, it should be nice.
@Community: if someone has some code to revamp the commentboxes on all sheets, please share it. 🙂
@Microsoft Excel-progammers: some pimpoptions for the commentboxes should be great.
Cheerio
Tom
For the auto run, please add the codes in workbook:
Private Sub Workbook_SheetActivate(ByVal Sh As Object)
Call Comments_Tom
End Sub
Wow, that was a lot of fun... Thanks Tom!
@Jeff... Now, 5000 people know about your favorite porn... 😛
@Tim ... you can write an event to handle the new comments. I wouldnt recommend it as it is really painful. another option is to use the macro suggested by Yukikomi. It will update comments everytime you activate the sheet.
@laguerriere: very cool 🙂
@Chandoo ... Thanks! This is good stuff. I combined your tip with a tip from Mark O'Brien, then assigned it to a button on Excel 2010's Quick Access Toolbar, to format comments AS I add them. I also like how Mark's code saves me the trouble of backspacing my name out of new comments:
Sub AppendToExistingComment()
'Source: Mark O'Brien at http://www.mrexcel.com/forum/showthread.php?t=57296
Dim oRange As Range
Dim oComment As Comment
Dim sText As String
'Use object variable to hold range.
Set oRange = ActiveCell
'Use object variable for comment
Set oComment = oRange.Comment
'text to be added to the comment box
sText = InputBox("Type text to be added:", "APPEND TO COMMENT TEXT")
If Len(sText) = 0 Then End
'If Active Cell has a comment then append new text to the end of the comment text
If Not oComment Is Nothing Then
sText = oComment.Text & vbNewLine & sText
oRange.Comment.Delete
End If
'Add a comment with the contents of sText
oRange.AddComment sText
DoEvents
Comments_Tom
End Sub
Thank you very much for the code, it seems to be working for the most part; I am having a problem however. Once the routine makes the corrections to the comment, the comment becomes invisible. By invisible, I mean that when I highlight my mouse over it, nothing appears. However, when I right click the cell and click 'edit comment' then the comment becomes visible and I enter edit mode. Upon clicking out of the comment, it simply vanishes again. I've tried to fix this problem by adding a .shape.visible = msoTrue but then every comment is always visible. o_O please advise...
Thank you,
Nick
@Nick- That is because the font color of the comment is white and when you select the color of selection is also white hence you can not see anything. Try to change the color code in the routine to something else. would work
Thanks for that! The code works perfectly!

@ Chandoo - code works great and the comments look super cool. But I have ran into a small issue. In the comments, I am inserting pictures. When I run the macro, for all comments which already have pictures; pictures are deleted. Pls help me retain the pics in comments.
[…] posted some code one of his readers submitted, it "pimps" your comment boxes from those boring black-text-on-yellow rectangles to something more professional and eye-pleasing. […]
love in it
Hi Tom,
This looks really excellent. I am however relatively new to macros / VBA codes so having copy pasted your code in the Developer mode of an Excel file, what are the next steps to use them? Can you please help? Just to recap, I opened a blank Excel workbook, clicked on Developer, copy pasted the comments code and saved the file to the desktop.
Now how do I go about using it to add comments to an existing file? My apologies for asking a question which may be basic to you great geniuses, but I am not there yet and aspire to get there.
Many thanks for helping me with next steps that I need to take so that I can now use the code.
Best Wishes

Dear Dave,
The best thing to do is to copy the macro in the personal.xls(x) file. The personal excel file will always be launched when you open excel so you can use it with every excelworkbook.
Read all about it on the page of Microsoft.
https://support.office.com/en-us/article/Copy-your-macros-to-a-Personal-Macro-Workbook-aa439b90-f836-4381-97f0-6e4c3f5ee566
Once you have the macro in the personal, you can 'call' the macro by the keyboardcombination 'alt+f8' and klik on the macroname.
Hope this clarifies the 'how to'. Good luck with your first steps in the wonderfull world of macro's.
Tom
Hi Tom,
Many thanks. I will try that out. Learning is fun and learning this stuff is even more amazing.

There is a line 'Dim LArea As Long' which does not appear to be used. Have I missed something?
Dear Gary,
Correct the 'Dim LArea As Long' is indeed not relevant and can be deleted.
Tom
Excellent hack!
For some reason when I opened my file after using LibreOffice Calc, all comment boxes had changed to some arrow shape.
So this macro helped me from manually changing more than 5000 comments in a worksheet, or having to install some Excel extension.
I used it with the following attributes to get back old style comments:
It helped me from manually changing more than 5000 comments in a worksheet, or having to install some Excel extension.
.Shape.AutoShapeType = msoShapeRectangle
.Shape.TextFrame.Characters.Font.Name = "Calibri"
.Shape.TextFrame.Characters.Font.Size = 10
.Shape.TextFrame.AutoMargins = True
.Shape.TextFrame.AutoSize = True
Thanks a lot!
This was helpful, thank you
I think this is among the most significant
information for me. And i am glad reading your article.
But wanna remark on some general things, The site style is great,
the articles is really great : D. Good job, cheers
Is there code to add to this that will format a particular part of the comment (i.e. make the last sentence in the comment bold and in italics)?
This is fantastic!
How would I add auto-sizing to it?
I tried adding this:
.Shape.AutoSize = True but it gives me an error and as a novice at VBA I can't figure it out.
.Shape.TextFrame.AutoSize = True
Hello I am so glad I found your web site, I really found you by accident,
while I was browsing on Bing for something else, Nonetheless I am here now and would
just like to say thanks a lot for a remarkable post and a all round entertaining blog (I also love the theme/design), I don’t have time to
read it all at the moment but I have book-marked
it and also added in your RSS feeds, so when I have time I will be back to read a lot more,
Please do keep up the fantastic work.
This is GREAT!
How should the code be changed in order to tun once for all worksheets in a workbook?
