Date Time Picker Field is a WordPress plugin that allows you to apply a simple Date and Time picker field to any input field using CSS Selectors.
After you install the plugin, go to the Settings page under Settings > DateTime Picker. There you’ll find the plugin options.
The most important thing to get started is to know the CSS selector of the input field that you want to apply the datetime picker. There are numerous youtube tutorials that describe techniques to do this, if you don’t know how yet.
Once you apply set the css selector and save the changes the plugin should convert that field into a date/time picker.
