The time factor is divided into many fractions of moments, hours, months, years, periods, seasons, etc. All the divisions in this verse are determined according to the astronomical calculations of Vedic literature. There are six seasons, called ṛtus, and there is the period of four months called cāturmāsya. Three periods of four months complete one year. According to Vedic astronomical calculations, there are thirteen months. The thirteenth month is called adhi-māsa or mala-māsa and is added every third year.

SB Canto 4

Everyone has to perform yajña according to the Vedic hymns. As stated in the Upaniṣads, fire, the altar, the auspicious full moon, the period of four months called cāturmāsya, the sacrificial animal, and the beverage called soma are necessary requisites, as are the specific hymns mentioned in the Vedas and composed of four letters.

SB 4.7.41, Purport:

In Bhagavad-gītā it is clearly said that yajña should be performed for Lord Viṣṇu. Lord Viṣṇu has one thousand popular, transcendental names, out of which one name is Yajña. It is clearly said that everything should be done for the satisfaction of Yajña, or Viṣṇu. All other actions a person may take are only causes for his bondage. Everyone has to perform yajña according to the Vedic hymns. As stated in the Upaniṣads, fire, the altar, the auspicious full moon, the period of four months called cāturmāsya, the sacrificial animal, and the beverage called soma are necessary requisites, as are the specific hymns mentioned in the Vedas and composed of four letters. One hymn is as follows: āśrāvayeti catur-akṣaraṁ astu śrauṣaḍ iti catur-akṣaraṁ yajeti dvābhyāṁ ye yajāmahaḥ. These mantras, chanted according to the śruti and smṛti literatures, are only to please Lord Viṣṇu. For the deliverance of those who are materially conditioned and attached to material enjoyment, performing yajña and following the rules and regulations of the four divisions of society and of spiritual life are recommended. It is said in the Viṣṇu Purāṇa that by offering sacrifice to Viṣṇu one can gradually be liberated. The whole target of life, therefore, is to please Lord Viṣṇu. That is yajña.
