How many days until autumn?
The timer will tell you how many days, hours, minutes, and seconds are left until the beginning of autumn.
Fall is not just a transitional season of the year. It is a time when we observe the fading of nature, see leaves falling, and enjoy the last warm rays of the sun. Days become shorter, and the air gets cooler. Many look forward to autumn to enjoy the bright palette of leaves, feel the tranquility and coziness of the first cold evenings.
When is the first day of fall?
📅 Calendar fall ties the dates for the start and end of autumn to the dates for the start and end of calendar months according to the Gregorian calendar. Usually, these months cross a certain threshold temperature (usually 0°C) dropping below. In the northern hemisphere, autumn begins on September 1, and in the southern hemisphere on March 1.
🌨️ Meteorological fall is based on reaching threshold temperatures (usually 0°C). The dates for the beginning and end are tied to the dates for the beginning and end of the months during which these threshold values are crossed according to the Gregorian calendar. In the northern hemisphere, autumn begins on September 1, and in the southern hemisphere on March 1. However, in polar and tropical regions temperatures may not cross these threshold values, and such countries usually do not have a classical division into seasons. Instead, they have a dry season and a rainy season.
🔭 Astronomical fall begins with the autumn equinox, when day and night are equal. This is usually September 22 or 23 in the northern hemisphere and March 22-23 in the southern.
When is the last day of fall?
📅 Gregorian fall in the northern hemisphere ends on November 30, and in the southern hemisphere on May 31.
🌨️ Meteorological fall ends when the temperature drops below a threshold value (usually 0°C). This happens in the northern hemisphere in November, and in the southern in May.
🔭 Astronomical fall continues until the winter solstice. Usually, this date falls on December 21-22 in the northern hemisphere and June 21-22 in the southern.
What is the day of the autumn equinox?
Equinox is the moment when day and night are of equal length, and the sun is exactly over the equator. It occurs twice a year. In the northern hemisphere, the autumn equinox is considered to be September 22 or 23, and in the southern hemisphere, March 20. The exact date of the autumn equinox is calculated using astronomical tables. The day of the autumn equinox is considered the astronomical beginning of autumn.
Why is autumn at different times in different hemispheres?
Autumn occurs at different times of the year in different hemispheres due to the tilt of the Earth's axis. As the Earth moves along its orbit around the Sun, the planet is alternately turned to it by the northern hemisphere and then by the southern. Therefore, when it is the warm season in one hemisphere, it is cold in the other. Since the concept of autumn is tied to temperature, when it is autumn in one hemisphere, it is spring in the other.
Why do seasons change?
The change of seasons occurs due to the change in the angle of incidence of sunlight during the Earth's orbit around the Sun. Earth orbits the Sun on an elliptical path, and this journey takes one year. Additionally, Earth rotates around its axis, which is tilted relative to the plane of orbit around the sun by about 23.5 degrees. This tilt leads to the fact that as the Earth moves along its orbit around the Sun, the angle of inclination of the sun's rays to the surface of the Earth changes, along with it the amount of energy reaching different parts of the planet.
This change in the amount of solar energy causes changes in the weather and climate that we observe as seasonal changes.
Interesting facts about autumn
- 🌲 Leaf fall: during autumn, trees shed their leaves, which is a protective reaction to the approaching cold.
- 🌜 Autumnal equinox: a day when the duration of day and night is almost the same, marking the beginning of astronomical autumn.
- 🐺 Preparation of animals for winter: in autumn, many animals prepare for winter hibernation, storing food and insulating their shelters.
Why is autumn so important?
- Autumn offers an opportunity to slow down and prepare for winter for both nature and us. It is a time when we can enjoy the last warm days, refresh our thoughts, and plan for winter. Autumn reminds us of the beauty of change and the importance of preparing for new conditions in our life.
Precautions in autumn
Autumn brings with it a change in weather, which can cause colds and allergies. It is important to dress according to the weather, avoiding hypothermia, and be prepared for seasonal allergies, having necessary medications. It is also important to use sunscreen on clear days, as ultraviolet rays become less intense. In some endemic regions, dangerous insects wake up from winter dormancy, such as ticks.
Enjoy autumn!
Autumn is a wonderful time for slowing down and planning for winter. It provides a unique opportunity to rediscover nature, start new projects, and take care of your physical and mental well-being. Use this time to spend it outdoors, planning a garden or just enjoying the last warm sunny days. Autumn is a chance to leave behind the hot days and fill your life with freshness and new ideas.
