See, in our country, every month of the calendar has been associated with some event and so each month has its own importance. There is also a special month called the Purushottama Maasa (literally meaning the month of Lord Vishnu) that is considered very special and important by the devotees of Lord Vishnu.
Devotees of Lord Shiva consider Shraavan to be most important. Devotees of the Mother Divine consider the months of Chaitra and Sharad (autumn) to be important. The festival of Navaratri is celebrated in the month of Sharad. So every month has its own significance and importance.
In our country we do not have a single school of thought or tradition when it comes to spirituality. There are so many sacred Puranas and scriptures, and each scripture prescribes something different and unique for each month of the year. But the essence of it all is that one should honour Time and give it due importance. Do not waste it unnecessarily on eating and drinking, or in useless gossip.
The message is that Time is sacred. Consider time as a Prasaad (a sacred offering) from the Divine.
