About

When sending an email, I would often include a sentence like "Tues Jan 21", only to find that Jan 21 was a Wednesday this year. Then I would have to send a follow up email clarifying whether you meant Tuesday the 20th or Wednesday the 21st.

This plugin watches updates to input fields, and if something that looks like a day of week plus date occurs, it looks for the closest one to the current date in the calendar, and makes sure the day lines up with the date. If it doesn't, it uses a simple popup alert.

After it alerts for one date it won't alert for it again unless the phrase is removed from the input box and put back. This allows user to edit it to fix, or to simply accept it because it was intentional.
