Calculate your circadian rhythm for free

Would you like to know why some days you feel as if anything is possible, while others you don’t even want to get out of bed? Each of us has our own rhythm, determined by the moment we are born.

Here you can calculate your personal circadian biorhythm. This is your"body clock", which begins to tick from the moment of your birth. Altogether, your biorhythm consists of three different lines: the physical, the emotional, and the mental, each with different lengths to their cycle.
