There is a lot of faith in Lord Subrahmanya in Hinduism! The day before Kumar Shashthi is called Skanda Panchami. Even if you do not have children, or there is a defect in the horoscope, it is believed that if you worship that God, you will definitely get the results. Therefore, Subrahmanya was born on the day of Kumarashti!
Once Shiva and Mother Parvati were in deep meditation. At that time Kamadeva disturbed their meditation. That's it! Shiva got very angry with Kamadeva. He immediately opened his third eye and burnt Kamadeva to ashes. At the same time, a light was produced from the penance of Shiva and Mother Parvati. Even the god of fire could not bear that light. So he flowed it into Mother Ganga, Mother Ganga also could not bear that light. Then Mother Earth accepted it, that light incarnated as Kumaraswamy.
Some people believe that Kumaraswamy was born on the Shashthi date of the month of Ashadha. Therefore that day is celebrated with great pomp as Kumaraswamy. Since Kumaraswamy was born with six faces, he is called Shasthmukha. Hence Shasthmukha is very dear to him. And he is very dear to Kumaraswamy, the day he was born in the month of Ashadha.
Kumarsashthi is celebrated for two days. The day before that is called Skanda Panchami. Fasting on this Panchami and worshipping the Lord on Kumarashthi brings good results. If you visit the Lord's temple on these two days, even if Validevasena's army is present, you will be blessed with a child. If you perform Abhishekam of the Lord or recite Subrahmanya Ashtakam on these days, you will still receive his blessings. If possible, it is good to keep a little offering near Nagar stones or a nearby mound and pour milk on it!
If you worship the Lord in this way on Skanda Panchami and Kumarasashthi, any doshas present in your horoscope are removed. If you want to have a child or gain wealth, you should worship God on this day. If you want success in court transactions or want to score good marks in upcoming exams, you should worship God on Skanda Panchami and Shashthi.
