Dates are managed through a '''dedicated calendar control''' in VtigerCRM. The control '''automatically suggests the current date''' while inserting new data or updating old ones. The suggestion is usually useful, but could prove annoying in specific contexts: forms containing a lot of date fields for example. Were the form filled with many date fields the user would be pressed to enter each one to correct or remove the unwanted suggestion. A similar scenario requires '''to update the calendar control standard behavior into suggesting a null value'''. The current date should be suggested only upon control explicit selection. Let's see how to update the standard date field behavior in '''release 5.2.1 of VtigerCRM'''.
