Emotional cycle
The emotional cycle lasts 28 days and is the second of the three biorhythm cycles. The classic method links it to mood, sensitivity and patience, that is, to how you react to people and situations. Fourteen days in the high phase, fourteen in the low one, with a critical day at every change of phase.
This cycle too goes back to Fliess, who called it the female cycle; Hermann Swoboda observed its periodicity in 1904 while studying how certain moods returned in his patients. Twenty-eight days are exactly four weeks: its critical days always fall on the same day of the week.
In the classic model this cycle is associated with the emotional dimension. In byourit’s overall score it has the same weight as the other two axes: the average is simple.
Here too the distance between two people's positions never changes, and at 28 days there is a case you can spot at once. If the two birth dates are 14 days apart, or 42, or 70, the two emotional cycles are always in opposite phases: one in the high phase while the other is in the low one, for life. If they are 28 days apart, or a multiple, the two cycles coincide day by day.
For someone born on 15 June 1990, on 2 September 2026 the emotional cycle is on day 13 of 28: still in the high phase, one day away from crossing into the low one.
