BeeMath exists to answer one deceptively simple question at the hive: given what I just saw, what happens next, and when?
Every honey bee runs on a fixed developmental clock. An egg hatches in three days; a worker is capped on day nine and emerges on day twenty-one; a queen emerges on day sixteen; a drone on day twenty-four. Beekeepers call this “bee math,” and it is the most useful mental model in the craft. Learn it and a frame of comb stops being a mystery and starts reading like a calendar.
What this site is
BeeMath is two things: a free hive-timeline calculator that turns a single observation and a date into projected lifecycle milestones and a recommended next inspection, and a library of long-form, evergreen guides that teach the reasoning behind those numbers. Everything here is built for adult hobbyist and sideline beekeepers who want to make better decisions with less guesswork.
How we approach accuracy
The development figures used throughout the site are the standard values taught in apiculture worldwide, measured at typical brood-nest temperature. Biology flexes a day or two with temperature, genetics and nutrition, so we present the math as a precise estimate and always encourage you to let your own bees have the final word. BeeMath provides educational information, not professional, veterinary, or legal advice.
