A seasonal routine; similar to the concept of dinacharya, but also accounting for the cycle of the seasons; rtucharya encourages us to adapt our personal routines to align more closely with the rhythms of the natural world, introducing practices and qualities that naturally promote balance all year long.

Rtu means synonym of time and charya means regimen to be followed.
The regimen which is wholesome to everyone with respect to diet and practices is called Rtucharya.
