Just want to know, if my PR approve, is it better to add another rule weekday ?

Thanks for your contribution!

Interesting idea, but the implementation seems limited to a specific date format.
Would it still work if the date format is 'January 25, 2025 15:04' or 'Jan 25, 2025'?

@nodivbyzero it utilize time.Parse, it should work.

The problem is according to doc, need to put 0x2C to represent comma
