In Europe, this is related to the English concept of Midsummer, High Summer or the Dog days, and related also to Spanish distinctions between primavera, estío and verano. The solar seasons change at the cross-quarter days, which are about 3–4 weeks earlier than the meteorological seasons and 6–7 weeks earlier than seasons starting at equinoxes and solstices. On the other hand, people living far to the west (America), whose clocks run behind UTC, may experience an equinox as early as March 19. People living farther to the east (Asia and Australia), whose local times are in advance, see the astronomical seasons apparently start later; for example, in Tonga (UTC+13), an equinox occurred on September 24, 1999, a date on which the equinox will not fall again until 2103. All the times are given in UTC (roughly speaking, the time at Greenwich, ignoring British Summer Time).
Such non-seasonal fluctuations are usually due to economic conditions and are often related to the “business cycle”; their period usually extends beyond a single year, and the fluctuations are usually of at least two years. In time series data, seasonality refers to the trends that occur at specific regular intervals less than a year, such as weekly, monthly, or quarterly. Any modern war of manoeuvre profits from firm ground – summer can provide dry conditions suitable for marching and transport, frozen snow in winter can also offer a reliable surface for a period, but spring thaws or autumn rains can inhibit campaigning.

By aligning offers with real-world holidays and weather trends, casinos can create timely reasons for players to stay active across several weeks instead of just one day. A really good way to find periodicity, including seasonality, in any regular series of data is to remove any overall trend first and then to inspect time periodicity. At progressively higher latitudes, the maximum periods of “midnight sun” and “polar night” are progressively longer. This also means that in many years of the twentieth century, the dates March 21, June 22, September 23, and December 22 were much more common, so older books teach (and older people may still remember) these dates.

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.
