Season and Astrology
The changes in seasons are considered when we talk about learning astrology. We will see in this article how the duration of a day changes.Seasons changes with the movement of Sun.Astrologically speaking the Sun on its movement towards northern hemisphere and when it approaches the vernal equinox or vasant sampat bindu, which is the first point of Aries on the intersection of celestial equator.The seasons start from this point.
Vasant Sampat Bindu (Vernal equinox)
The Sun exactly rises from east on 21st March. Post this it starts going to the northern hemisphere. This is known as Basant Sampat. This is because it happens in the Basant (spring) season in the presence of Sayan-Mesh combination. The sun in this period rises from the east and day-night are of equal duration. This means that the sun rise at exactly 6 AM in the morning. Nadivrat and Krantivrat intersect each other. The intersecting point is used to calculate bhogansh and vishupakshi. This point is also known as Sayan-Aries bindu or Uttari Sampat bindu.The entry of the sun in the first point of Aries is the day considered by the Hindus when Lord Brahma created this universe.New plantation growth begins,animals start giving birth to their new generation,birds start making their nest, gardens are full of flowers.
Grishma Krantibindu (Summer Solstice)
The Sun is near the Grishma Krantibindu around 21st June. The Sun travels to this point after travelling through the northern hemisphere from Sayan-Mesh. During this period, sun rays form a triangle on the Cancer sign. During this time, the Sun is very far from the Vishuvat line and the duration of the days are longer than nights. This is known as Sayan-Cancer Sankraman. Post this, the Sun completes its journey in the northern hemisphere and reaches Sayan-Libra. This happens around 21st June.
The sun travels to the southern hemisphere after reaching this point. This is the reason why Grishma Kranti is also known as Dakshinayan bindu.This is the time when growth has taken place, harvest is ready and time to celebrate the hard work done to get it.
Sharad Sampat Bindu (Autumnal equinox)
This is the second intersecting point of Nadivrat and Krantivrat. Around 21st September, the sun travels the northern hemisphere and reaches a point which is known as Sayan -Libra. This takes about six months. The sun returns to Vishuvat and rises from the east. The duration of day and night are equal. Then, the sun travels in the southern hemisphere and this journey is also known as Dakshin Sampat. Sharad (Autumn) seasons starts. The Sun stays from Sayan-Aries to Sayan-Libra in the northern hemisphere and from Sayan-Libra to Sayan-Aries in the southern hemisphere.It is the time to prepare for the winter with long nights. Food and other items need to be stored for the harsh winter coming next.
Sharad Kranti-Uttarayan Bindu (Winter Solstice)
This happens on the 21st December when the Sun is far from Vishuvat line in the southern hemisphere. This is the time when plants begin to shed their leaves and old things die to give way for the arrival of the new.This is the southern border of Kranti Vrat. Sun rays form a triangle when they fall on Capricorn line around 22nd December. During this time, Sayan is in Capricorn sign. Dakshin Kranti of sun is between 23 and 28 degrees during this period. The sun rises at 25 degrees in the east on this day. The sun starts travelling north from this day. The night time is the longest on this day. This is the beginning of Uttarayan. This is the reason why this is also known as Uttarayan Bindu.Uttarayan has a special meaning in Hindu traditions.It is widely celebrated as it will again start the period of new beginning after sometime and preparations have to start at the earliest.
