Due date calculator
This simple tool can show you
what a woman’s due date will be.
See page 88 to learn more
about due dates.
Copy this page and paste it
onto a piece of cardboard or
stiff paper. Then cut the circles out.
Put the smaller circle on top of
the larger circle and fasten them
together through the center.
To use the wheel, point the
arrow that says “last monthly
bleeding” to the first day of the
woman’s last monthly bleeding.
The other arrow will then be
pointing to the baby’s estimated
date of birth.
