Until I get my new Jonas software, here's an easy-ish way to calculate your own Jonas Ovulation dates.
I'll use Angelina Jolie as an example.
====================================================================
Angelina Jolie - June, 4, 1975 - 9:09AM - Los Angeles, California
Open one of these 3 links, whichever you find easiest;
http://www.timeanddate.com/calendar/moonphases.html <--- I like this one best, it's used in my example.
(http://www.timeanddate.com/calendar/generate.html or http://aa.usno.navy.mil/data/docs/MoonPhase.php) <---These will do in a pinch
We enter Angie's year of birth, 1975, in Los Angeles, CA, and click Show Moon Phases.
Now we have our 1975 calendar.
We look on the calendar for the date closest to her birthday, June 4, which is 'June 1, 4:22 PM' under the column Third Quarter (aka Last Quarter)
From 'Jun 1, 4:22 PM' the Last Quarter to 'June 4, 9:09 AM' her birthdate is 2 days - 16 hours - 47 minutes.
Thus 2 days - 16 hours - 47 minutes after every Last Quarter moon is Angie's personal Sun/Moon phase Angle. This is the exact time Dr. Jonas predicted a woman would ovulate.
(Note this is an ovulation period completely separate from the regular menstrual cycle. Even if Angie is on her period, Dr Jonas believed that she would ovulate at this date/time)
So, let's calculate her Sun/Moon Jonas date for August 2009 in Los Angeles, CA. (Note: If Angie was living in Paris France in August, we would calculate for Paris France) But for our purposes, I will use Los Angeles.
So let's go back to the moon phase calendar site and calculate for 2009 in Los Angeles, CA.
Now we have our year 2009 chart.
The third Quarter (aka Last Quarter) in August is listed as 'Aug 13, 11:55 AM'
Now remember that Angie's personal Jonas date is 2 days - 16 hours - 47 minutes after each Last Quarter moon.
So I add 2 days, 16 hours, and 47 minutes to Aug 13, 11:55AM and I get Aug 16, 4:42am.
This is when Dr. Jonas predicts Angie will ovulate in August 2009.
========================================================
And there you have it. The manual way to calculate your personal Sun/Moon-Jonas-ovulation date each month!
Is that not the biggest buttpain you've ever seen? haha! But it can be done.
I really, really, really, don't want to do that for everyone because it hurts my brain. But I will answer any questions you have about the method or calculations, etc.
