Hello, 

When using a (https://www.docusign.com/support/classic/documentation/cdse-user-guide/docusign-tags/docusign-tags#DataField) Data Field or (https://www.docusign.com/support/classic/documentation/cdse-user-guide/docusign-tags/create-tag) Custom Tag   witha a Date Mask:

• t he tooltip will recommend that the signer enter the date as MM/DD/YYYY, but this  is NOT enforced when using any date formats that include month text. (e.g. 10 Nov 2015 or November 10 15) Although the Tool Tip will say that it is an invalid date, it will allow the signer to complete signing. 
• The MM/DD/YYYY  IS enforced when using an all numerical date format. It will not let the signer enter a date that is not in  MM/DD/YYYY (e.g 15 /10/2015 , 15/10/2015 are blocked)

*If you are familiar with (https://support.docusign.com/answers/00001589) Regex , you may be able to use the Text Mask with a Custom Regex Pattern, to create the desired format. 

Please Note: This is not to be confused with our (https://support.docusign.com/answers/00002637) Date Signed Tag,  that supports multiple formats. 

I hope this helps.

**If you create a format with a custom Regex Pattern, please share with the community below. 

If you want only the format date : mm-dd-yyyy, you may use this regex :

^(0[1-9]|1[0-2])-([1-9]|[12][0-9]|3[01])-(\\d{4})$

DocuSign

Here is something for yyyy-mm-dd, which is common in Canada and probably elsewhere. It accepts Feb 29 in any year but it would be pretty easy to add a bunch more to cope with Feb 29 every 4 years in the 20th and 21st centuries.

^19|20\\d{2}-((01|03|05|07|08|10|12)-(([012]\\d)|30|31))|((04|06|09|11)-(([012]\\d)|30))|((02)-(([012]\\d)))$

Ooops. Posted that too soon - it allowed for 00 days!

^(19|20\\d{2})-(((01|03|05|07|08|10|12)-((0[1-9])|([12]\\d)|30|31))|((04|06|09|11)-((0[1-9])|([12]\\d)|30))|(02-((0[1-9])|(1\\d)|(2[0-9]))))$
