Apart from the Navratri in September – October, there are three other Navratris in a year. The most important among the three is the Chaitra Navratri or the Navaratri in March-April. This is also known as Vasant Navratri or Ram Navaratri.
The other two Navratris are Magh Navratri (January – February) and Ashad Navratri (June – July). These two Navratris are also known as Gupt Navratri and is mainly observed only in certain regions of North India.
Thus there are four important Navratris in a year in a traditional Hindu lunar calendar.
