Zodiac Baby Planner

Calculate conception dates for any zodiac sign, including optimal TTC dates.

About this Baby Planning Calculator

This calculator takes the zodiac you select, and uses that zodiac's birthday range (for example, a person born from May 22 to June 21 is a Gemini) to reverse calculate when you would need to conceive in order for your baby to be born under that zodiac sign. It factors in if it's a leap year, and where we are in the current year.
