Planting Data

[magdesign]

Hi.
Thanks for making this amazing project.
We are just on the go to implement moon phases in Calcure calender app and i came up with the idea to create a digital seed calender similar to the calenders we get from Demeter or Maria Thun.

Thats how i found your tool. i know you focus is on logging.
However, does anybody know how to get opendata for when to seed and harvest plants?
Anyone good on Astrology and knows how to calculate such things?
It seems to me its a big closed source blob which needs to be set free.
Knowledge must be accessible for everyone.
Thanks.
