Use this free ovulation date calculator and calendar to estimate your ovulation day, fertile window, next period, and best days to conceive.


Does this only work off cycle length averages or can you log actual BBT and OPK results to get a more accurate fertile window?
Does this just estimate based on cycle length or does it actually track BBT or LH data for more accurate fertile window predictions?
Simple layout and the fertile window estimate lined up well with what I was tracking on my own. Wish it remembered my cycle length between visits.
Clean and straightforward, no clutter or upsells. The fertile window estimate lined up well with what my doctor gave me.
This is honestly the first ovulation calculator I have not had to dig through ads to actually use. Liked that it shows the fertile window alongside the next period estimate, made timing feel way less like guesswork.
The calendar layout is genuinely well thought out, showing the fertile window and ovulation day right alongside the cycle dates instead of burying them in a separate screen. Nice work making something that could feel clinical actually feel approachable.
