Spacefem.com: Daily Pregnancy Calendar
Enter your LMP or due date, and this tool will quickly generate a bookmarkable page that:
- Tracks how far along you are in weeks, days, months, and percent
- Calculates your due date, if you don't know it
- Estimates your current odds of going into spontaneous labor (after 35 weeks)
- Reports average fetal size and weight for where you're at (after 7 weeks)
- Links to a few popular weekly pregnancy blogs I found, including our own weekly pregnancy blog here at spacefem.com
- Recommends a daily wikipedia article about pregnancy, childbirth, or infant care
With no fluff, advertisements, or cuteness! It's quite possibly the most useful pregnancy tracker ever, and definitely the nerdiest.

How does this work?
says that a baby is most likely to show up around 40 weeks (280 days) after your last menstrual period. So this script adds 280 days. If you're really a nerd, here's the PHP code to figure up a due date:
$lmptimestamp = mktime(12,0,0,$lmpmonth,$lmpday,$lmpyear);
$duedate = date('r',$lmptimestamp + 280*24*60*60);

How do you find out how far along you are?
To find weeks: find out how many days along you are (simple subtraction) and dividing by 7.
To find months: find out how many days along you are and divide by 365.25/12 = 30.4375 (average number of days in a month)
How do you convert weeks into months?
Months = weeks * ([7 days in a week]/[365.25 days in a year]) * [12 months in a year] = weeks / 4.35
You will notice I did not say "divide by 4". This is because there are not four weeks in a month. A month is not 28 days. A lunar month is not 28 days. There's no such thing as a special pregnancy month that's 28 days. Pregnancy does not last ten months, unless you're a terribly slow incubator. This is all sort of a big pet peeve of mine. If you're going to bring new life into the world, check your math.
