From Nicaea to the date of the reform, the years 500, 600, 700, 900, 1000, 1100, 1300, 1400, and 1500, which would not have been leap years in the Gregorian calendar, amount to nine extra days, but astronomers directed that ten days be removed. The times of the equinoxes and solstices are not fixed with respect to the modern Gregorian calendar, but fall about six hours later every year, amounting to one full day in four years. Thus the time from the March equinox to the September equinox is 7.56 days longer than from the September equinox to the March equinox. From the March equinox it currently takes 92.75 days until the June solstice, then 93.65 days until the September equinox, 89.85 days until the December solstice and finally 88.99 days until the March equinox. The precise timing of the seasons is determined by the exact times of the Sun reaching the tropics of Cancer and Capricorn for the solstices and the times of the Sun’s transit over the equator for the equinoxes, or a traditional date close to these times. He points out that the lengths are not equal, being 91 (in non-leap years), 94, 91, and 89 days for spring, summer, autumn, and winter, respectively.
Every periodic function can be approximated with the inclusion of Fourier terms. However, the seasonality of such a regression would be represented as the sum of sine or cosine terms, instead of a single sine or cosine term in a sinusoidal model. Similar to using the sinusoidal model, Fourier terms added into regression models utilize sine and cosine terms in order to simulate seasonality. A less completely regular cyclic variation might be dealt with by using a special form of an ARIMA model which can be structured so as to treat cyclic variations semi-explicitly. The index is based on a mean of 100, with the degree of seasonality measured by variations away from the base. An index value is attached to each period of the time series within a year.

As mentioned above, Varro wrote that spring, summer, autumn, and winter start on the 23rd day of the Sun’s passage through Aquarius, Taurus, Leo, and Scorpio, respectively, and that (in the Julian Calendar) these days were February 7, May 9, August 11, and November 10. Astronomical timing as the basis for designating the temperate seasons dates back at least to the Julian Calendar used by the ancient Romans. The beginning of spring is defined as when the mean daily temperature permanently rises above 0 °C.

“Higher supply over the next few weeks and cooler weather may mark a seasonal low for Nymex gas futures before they recover in the autumn.” Seasonal things happen periodically, during a certain season. Seasonal and seasonable are sometimes interchanged, probably because of their obvious connection with season. The resulting seasonally adjusted data are used, for example, when analyzing or reporting non-seasonal trends over durations rather longer than the seasonal period.

For example, for monthly data, if there is a seasonality effect, we would expect to see significant peaks at lag 12, 24, 36, and so on (although the intensity may decrease the further out we go). However, if the period is not known, the autocorrelation plot can help. Apart from these considerations, the organisations need to know if variation they have experienced has been more or less than the expected amount, beyond what the usual seasonal variations account for.
- The low angle of the Sun during the winter months means that incoming rays of solar radiation are spread over a larger area of the Earth’s surface, so the light received is more indirect and of lower intensity.

In Sweden and Finland, meteorologists and news outlets use the concept of thermal seasons, which are defined based on mean daily temperatures. In 1780 the Societas Meteorologica Palatina (which became defunct in 1795), an early international organization for meteorology, defined seasons as groupings of three whole months as identified by the Gregorian calendar. These observances are often declared “official” within their respective areas by the local or national media, even when the weather or climate is contradictory. Nine years before he wrote, Julius Caesar had reformed the calendar, so Varro was able to assign the dates of February 7, May 9, August 11, and November 10 to the start of spring, summer, autumn, and winter.
