Seasonal calendar

Greetings

Reading northern hemisphere books pertaining to planting/harvesting/pruning/horticultural practices/gardening/permaculture design etc. in the southern hemisphere can be confusing with reference to the months/seasons. This is due to the  six month offset of the months/seasons and the differences between the meteorological and astronomical definitions of the seasons.

Meteorologists divide seasons into periods of three whole months based on average monthly temperatures. Astronomers define seasons with two solstices (shortest day and longest day) and two equinoxes (when day time and night time are of equal length). Astronomers use the earth's tilt and the sun's alignment over the equator to determine the dates for each event.

The table below has been designed to facilitate interpretation of months and seasons for each hemisphere and seasonal definition.
