• 1

  The Conception Date Calculator applies the standard accepted formula to the values you enter, so the result is only as good as its inputs — fill every field in one consistent unit system and re-check any value copied from another source.

• 2

  Enter values in the units the Conception Date fields expect; mismatched units are the most common way a correct formula yields a wrong number no calculator can detect.

• 3

  Round only at the end: Conception Date carries full precision internally, so rounding intermediate values by hand can shift the final answer more than the accuracy of the formula itself ever would.

• Entering values in the wrong field is the top error on a Conception Date page: adjacent inputs accept any number, so a swapped or shifted value still produces a plausible-looking result. Read each label against your data before calculating.

• Mixed units skew a Conception Date silently: the standard formula assumes one unit system across all inputs, and no warning fires when centimeters meet meters or months meet years. Standardize every input to its field's stated unit first.
