Hi, this is the correct format I need. The date is written December 18, 2020 and I need it to convert to 18-Dec-2020. Can you help me with that please?

Ditty, this regex does indeed account for leap years as shown in the last sample match and non-match.

Thanks for the catch but the fix to allow Sep is not just placing a ? after Sept. That would allow Sepember to pass. Each instance of Sept would need to be Sep(?=\b|t)t?
(?i:) will only work in serverside code.
The options are not allowed in the pattern in JScipt, so what is valid serverside may not be clientside.  I don't know how Asp.Net dealing with embedded options.

tiny bug: Sep is rejected because ? is missing after Sept.
What modification is needed to make this case insensitive?
I tried adding ^(?i)( etc...
at the beginning, and it works in some environments, but not as an ASP ValidationExpression 
System.Web.UI.WebControls.RegularExpressionValidator
Visual Studio allows the syntax to be entered, but the debugger catches it.
This is off the topic of the expression per se, but I thought I'd ask.  
Thanks for the expression!

Exactly what I was looking for given that date validation in "UK" format doesn't work properly in the ASP.NET validation controls.  Worked first time, thank you very much indeed.
