Until 2009, it was thought that 28 cycles had spanned the 309 years between 1699 and 2008, giving an average length of 11.04 years, but research then showed that the longest of these (1784–1799) may actually have been two cycles. [18] [19] If so then the average length would be only around 10.7 years. Since observations began cycles as short ...
Prehistory – Period between the appearance of Homo ("humans"; first stone tools c. three million years ago) and the invention of writing systems (for the Ancient Near East: c. five thousand years ago).

This prediction is in line with the current general agreement in the scientific literature, which holds that solar cycle 25 will be weaker than average (i.e. weaker than during the exceptionally strong Modern Maximum). [7] However, observations from 2020 to 2022, the first three years of the cycle, significantly exceed predicted values. [12]

El Niño phases are known to happen at irregular intervals of two to seven years, and lasts nine months to two years. [48] The average period length is five years. When this warming occurs for seven to nine months, it is classified as El Niño "conditions"; when its duration is longer, it is classified as an El Niño "episode". [49]
The Sadesati will continue while Saturn transits over this sign and the next two signs, i.e. the birth sign and the sign after it. Saturn spends around 2 + 1 ⁄ 2 years in each sign. To cross these three signs it takes about 7 + 1 ⁄ 2 years. Thus the name Sadesati which literally means seven and a half. [citation needed]
