What Date? is a simple, freeware date calculator for Windows. Enter a date and interval and press calculate to find any date in the future or past. What Date will recognize any date format which Windows can understand (date formats as set in Control Panel). I wrote this because many people emailed asking; Is there a simple way to find a date given a start date and interval?.
Community Volunteer. Your due date indicates ovulation/conception around Feb 26. Sex between about Feb 21 and Feb 27. How accurate this is will depend on how and when your due date was determined. It looks like Mr Feb24 (another ex) is the likely dad.
