This a queen rearing app for beekeepers. It calculates the dates for all the steps need in the rearing of queens. There are several methods to choose from in the app settings. There is a brief explanation of each step. It is possible to use any step as the starting point for the calculation. Once the dates for a queen rearing series have been calculated, the app can send an e-mail to the user with all the dates in the message text as well as in iCalendar file, that can be imported into Outlook or iCal. More methods can be added as I receive feedback from the users and suggestions from other breeders.
