Other factors (e.g. stress) can result in ovulation being delayed, until as late as the third or fourth week. However, the way our care providers calculate pregnancy due dates is by assuming ovulation on day 14 of a 28 day cycle. You can already see a major reason why due dates aren't so accurate!
Time of ovulation. Women often believe that ovulation occurs mid-cycle. It actually occurs 12-16 days before the next period starts. So, although a woman with a 28-day cycle may ovulate mid-cycle (between day 12 and day 16), a woman with a 36-day cycle will ovulate between day 20 and day 24. For women with regular cycles, an easy way to approximate the time of ovulation is to subtract 16 from the number of days in the cycle and then add 4.
