Date picker is a control from current versions of Word that contains a date entry field. The date is selected by the user from the drop-down calendar and inserted into the field in the specified format. Entering the date manually is not allowed.
The date in the input field can be formatted. For example, change the size and color, make it underlined, apply a preset style to the date. As the font size increases, the size of the date input field changes proportionally.
