I like having all this in one place, and where there are real-world examples. You should be writing the docs on Microsoft.
URLs are broken.
Nuno,
Which URLs do not work? It would be more helpful if you can tell me how to reproduce the issue.
Thank you, this is a comprehensive documentation to check for date and time functions.
I wish you have added an example about an age calculation as part of the examples. Last week I had to calculate an age with Year and months and used the below formula. Look forward to hear from you if there is a shorter version to the below formula.
If(
!IsBlank(varRecord.DOB),
If(
DateDiff(
Today(),
Date(
Year(Now()),
Month(lbl_DOB.Text),
Day(lbl_DOB.Text)
)
) Month(lbl_DOB.Text),
Month(Today()) – Month(lbl_DOB.Text),
Month(Today()) = Month(lbl_DOB.Text) && (Day(Today()) >= Day(lbl_DOB.Text)),
“0”,
Month(Today()) + 12 – Month(lbl_DOB.Text)
) & ” month(s)”,
“”
)
Hi Matthew, started reading your articles recently and I am loving them thank you very much.
I don’t know if I am explaining this well, but I am trying to create an app using power apps and I need help with date manipulation.
How can I set up a particular date and time a service will be available and the date it would end without being able to bypass it example the date a room will be available in a hotel and the amount of days the room will be available and can not exceed that time. Thank you
Rachel,
Great question! I think its going to be a little bit long to describe in the comments section here. So I think the best way to communicate how to do this would be to watch this video by my good friend April Dunham (https://www.youtube.com/watch?v=zroxwXpVhHI). She made a ‘desk book reservation system’ and shows how it was built in the video. You can even download a copy of the app to inspect it.
I am considering writing a ‘booking system’ app for my own blog. If you have any other requirements let me know and I’ll see what features I can include when I get to writing it.
Hi Matthew, your articles are great. I’m using the one on “Edit A Record With A Patch Form” and am running into some issues with dates, radio buttons, and people. Everything is fine until I create the submit button. It then breaks my gallery and a couple of labels on my submit form. The purpose of the app is for someone to review a procedure and say whether it is accurate or not. So I’m just passing the record variable through for the document number and title into a label. I want the Radio to default to blank, the reviewer to be auto filled to current user(Label Text is: User().FullName), and the date to be auto filled(Default date is Today()).
The doc number and title are text in SP, Radio is a Choice, Date is Date/Time, and Reviewer is Person or Group.
Here is the code in the submit button:
// submit the form data
Set( //<– new code
varCurrentRecord,
Patch(
‘Finishing LOTO Updates’,
varCurrentRecord, // <– new code
{
DocumentNumber: GalDocNumber.Text,
DocumentTitle: GalDocName.Text,
ProcedureIsAccurate: Radio1.Selected.Value,
Reviewer: ‘Current User_1’.Text,
DateofLastReview: DatePicker1.SelectedDate
}
)
)
What am I doing wrong? Thanks!
Jeremy,
Would you please repost this under the related article “Everything You Need To Know About Power Apps Patch Forms.” I can’t manually move this post and I’d like to try to keep the chats “on-topic” for each article.
Thanks in advance. I’ll await your reply.
Awesome resource. – Thanks, Matthew!
Jason,
Thanks for the kind words!
Hi
I have 3 Labels.
Label1 -StartTime
Label2-EndTime
Label3- Date Diff (Hours : Minutes)
Label1&2 I have used – Text(Now(), “[$-en-US]mm/ddd/yyyy hh:mm AM/PM”)
request you help me to achieve DateDiff in Hours : Minutes
Thanks & Regards
Bujjibabu KJ
Bujj,
The solution is:
Text(DateDiff(StartTime, EndTime, Hours))&”:”Text(Mod(DateDiff(StartTime, EndTime, Minutes),60))
Great article! THANS!
Ihave an issue trying to inform the Form Submission time into email body, sent by my Flow. The submission date/time of my form, loaded in my SP list, looks ok, is the real date time value, BUT I can’t show it correctly in my email body. Sometimes is correct, most times is 2 hours back… What am I doing wrong? Why is it variable?
I’ve tried to use the form value (submission time), and also directly the sharepoint list field…..all in same Flow, after loading my SP list.
Any help will be appreciated.
Thanks!
Luis,
I’m glad you liked the article. Suggest you visit the community forums for the answer to your flow question:

Thank you very much for your post and time invest, really works for me.
Juan,
You’re welcome 🙂
