The same could be true of humans, Kopas says, but there’s not enough solid evidence to say one way or another. To get this timing right, certain species have evolved to the point where females only go into estrus (aka heat) during specific seasons. In the animal kingdom, many newborns emerge right around springtime, when food sources are plentiful again and the likelihood of survival is much higher. In your imagination that little white-tailed fawn is probably frolicking in a grassy meadow studded with wildflowers - and there’s a reason for that. Why more babies are conceived in fall and winterĬlose your eyes for a moment and picture Bambi. Kopas shares her thoughts on the matter as well as some helpful facts for what to know if you hope to get pregnant this winter. Is it the cozy sweater weather that’s causing us to turn up the heat? Do our longer nights have something to do with it? Or is it something biological that we just can’t explain? That means prime conception time in the United States occurs in fall and winter. According to the National Center for Health Statistics, more babies are born in northern states like Washington around June and July, while southern states experience a peak a bit later in October and November.

The evidence isn’t purely anecdotal, either. “Count back nine months and, well, we’re looking at November to January.” “We typically have more babies born in July, August and September,” says Mary Lou Kopas, chief of midwifery at University of Washington Medical Center - Northwest. Continue the procedure until the ninth month.You’ve probably heard those stories about how a Super Bowl win or a city-halting snowstorm led to a mini baby boom, but did you know there’s actually a season when more babies are conceived? The calculation has to be done stepwise starting from subtracting the due date from 266 and then subtracting the difference with the total number of days the following month. Although all you will need to do is the delivery due date to be subtracted from 266 days, the calculation can be fairly complicated. The reverse calendar calculator helps in getting to a time window, if not a specific day or date with a bit of mathematics. However, it is not possible to mark the exact day of ovulation since the ovulation cycle starts from the 11 th day and continues until the 21 st day of the monthly cycle. How Does the Reverse Due Date Prediction Method Work?įor women who know their due date, it is easy to estimate the time frame when they might have conceived. Therefore in such cases, the reverse conception calculator tool helps in knowing the exact time frame as to when the pregnancy began. However, this method is not accurate always since many women may not have a 28-day cycle.


A woman who is curious to know when her mother might have conceived her or if you want to know about the time of your little one’s conception, the reverse birth calculator can help.
