As per Ayurveda 2-6 pm in the evening and 2-6 am in the morning is period of Vata or creativity. Most poets and writers would do their creative work at that time of the day especially 2-6 am in the morning.

Vata period is more creative and you are less likely to make mistakes. Four PM in the evening is considered the best time to make a deal, sign a document or to send a confession note.

Apart from the time of the day Vata age is old age and Vata month is rainy season. This is one reason that we always pay attention to the advice of the elderly.
