This article is part of the Tool Mastery Series, a compilation of Knowledge Base contributions to introduce diverse working examples for Designer Tools. Here we’ll delve into uses of the DateTime Toolon our way to mastering the Alteryx Designer:
Date/Time data can appear in your data in string formats (text fields) or date formats.The DateTime Tool standardizes and formats suchdata so that it can be used in expressions and functions from the Formula or Filter Tools (e.g. calculating the number of days that have elapsed since a start date). It can also be used to convert dates in datetime format to strings to use for reporting purposes.
The functionality of the DateTime tool is very similar to the DateTime Functions in the Formula Tool, but a little more user-friendly.
To change a date datatype to a formatted string field, all you do is select the date field to be formatted, what you would like the formatted date to look like and the name of the new field Alteryx will create:
Converting a date contained in a text field to a proper date format works similarly: you select the field to be formatted, the string that matches the current format and what the output field should be called.
A date stored as date format will always appear as yyyy-mm-dd when viewed in a Browse Tool .
The dy., Month dd, yyyy and day, dd Month, yyyy options allow you to output the day of the week. This is especially useful if you want to differentiate between weekends and weekdays, e.g. if you want to remove business days from your data (if you only have the start and end dates and want to remove business days, refer to this article).
If the DateTime tool doesn't cover your needs, go over to this article and this post to explore the options using Date/Time functions in the Formula Tool.
By now, you should have expert-level proficiency with the DateTime Tool! If you can think of a use case we left out, feel free to use the comments section below!

The links have been fixed, thank you for bringing this to our attention!
You're welcome!
More precision (milliseconds and perhaps also nanoseconds) hopefully coming later this year: https://community.alteryx.com/t5/Alteryx-Designer-Ideas/Add-DateTime-type-with-milliseconds/idi-p/20...
Is it possible to clear the Input Data conversion error of ______ "is not a valid DateTime"? When I place the DateTime toll directly after the Input tool and run, it works perfectly, but I'm still left with that input error. Is this normal? Thanks so much!
Hi @Gina2021
That error is telling you that you have an invalid date in your data that it can't convert.
It will create a null value for the value that it can't convert and process the rest of the data. If you don't mind that, you can just ignore the conversion error.
Ooohhh! That explains why I have so many null dates! So are users finding ways to fix the date format upstream? I'm pulling in an Access DB. Thanks!
Hi @Gina2021
It's hard to say without looking at the data. It could be inconsistent formatting? E.g. some dates are formatted as mm/dd/yyyy and others as yyyy-mm-dd
You could use the data profiling tool to take a look at the dates to see what they look like.
You can also use the formula tool to too format dates. This article gives some good examples: https://community.alteryx.com/t5/Alteryx-Designer-Knowledge-Base/When-Time-is-of-the-Essence-Using-D...
Amazing @HenrietteH ! Thanks so much!
I'm trying to convert this Ship Date quantity to be a Date, however I am running into errors. Not sure what is wrong?
@skomaragiri It looks like your date is coming in as a string with the quotes around it.

Hello All,
I am trying to calculate a date back on time. I need to set up first to use the date from an specific column on month back. And once it is calculated (Ex From August to July 2021) then calculate 5, 10, 15 and 20 years.
Could some one help me with this? I've been trying for a while but I can't get any positive result,
Thank you in advance

Interesting and very helpful. Thank you.
thanksxplanation for this

Thank you so must and helpful in date time
I have a mixture of date and time format in GMT timings example if it says 3/10/2000 23:00:00 the actual date would be 4/10/2000. If the data is 3/10/2000 00:00:00 then no changes required.

The Date Time Parse link above gives this error:
Which link exactly gives you the error?
I just went through all the links in the article and they all work for me but I may have missed one.
Some of them now point to the new Knowledge Base maybe you don't have access to that?
