"twelve thousand years"

SB Canto 2

The four yugas are calculated in terms of the heavenly calendars and accordingly are twelve thousand years in terms of the heavenly planets. This is called a divya-yuga, and one thousand divya-yugas make one day of Brahmā.

SB 2.10.46, Purport:

In the upper planetary system the duration of one complete day and night is equal to one complete year of this earth. This is accepted even by the modern scientist and attested by the astronauts. Similarly, in the region of still higher planetary systems the duration of day and night is still greater than in the heavenly planets. The four yugas are calculated in terms of the heavenly calendars and accordingly are twelve thousand years in terms of the heavenly planets. This is called a divya-yuga, and one thousand divya-yugas make one day of Brahmā. The creation during the day of Brahmā is called kalpa, and the creation of Brahmā is called vikalpa. When vikalpas are made possible by the breathing of Mahā-Viṣṇu, this is called a mahā-kalpa. There are regular and systematic cycles of these mahā-kalpas, vikalpas and kalpas.

SB Canto 3

SB 3.11.18, Translation:

Maitreya said: O Vidura, the four millenniums are called the Satya, Tretā, Dvāpara and Kali yugas. The aggregate number of years of all of these combined is equal to twelve thousand years of the demigods.

SB Canto 10.1 to 10.13

Twelve thousand years on the celestial planets is not a very long time for those who live in the upper planetary system, although it may be very long for those who live on this planet.

SB 10.3.37-38, Purport:

Twelve thousand years on the celestial planets is not a very long time for those who live in the upper planetary system, although it may be very long for those who live on this planet. Sutapā was the son of Brahmā, and as we have already understood from Bhagavad-gītā (8.17), one day of Brahmā equals many millions of years according to our calculation (sahasra-yuga-paryantam ahar yad brahmaṇo viduḥ). We should be careful to understand that to get Kṛṣṇa as one's son, one must undergo such great austerities. If we want to get the Supreme Personality of Godhead to become one of us in this material world, this requires great penance, but if we want to go back to Kṛṣṇa (tyaktvā dehaṁ punar janma naiti mām eti so 'rjuna (BG 4.9)), we need only understand Him and love Him. Through love only, we can very easily go back home, back to Godhead. Śrī Caitanya Mahāprabhu therefore declared, premā pum-artho mahān: love of Godhead is the highest achievement for anyone.

Krsna, The Supreme Personality of Godhead

On hearing the prayers of Devakī, the Lord replied, "Both of you practiced severe austerities for twelve thousand years by the calculation of the demigods. During that time, your mind was always absorbed in Me. When you were executing devotional service and always thinking of Me within your heart, I was very much pleased with you."

Krsna Book 3:

On hearing the prayers of Devakī, the Lord replied, "My dear mother, in the millennium of Svāyambhuva Manu, My father Vasudeva was living as one of the Prajāpatis. His name at that time was Sutapā, and you were his wife named Pṛśni. At that time, when Lord Brahmā was desiring to increase the population, he requested you to generate offspring. You controlled your senses and performed severe austerities. By practicing the breathing exercises of the yoga system, both you and your husband could tolerate all the influences of the material laws: the rainy season, the onslaught of the wind, and the scorching heat of the sunshine. You also executed all religious principles. In this way you were able to cleanse your heart and control the influences of the material laws. In executing your austerity, you used to eat only the leaves of the trees which fell to the ground. Then with a steady mind and controlled sex drive, you worshiped Me, desiring some wonderful benediction from Me. Both of you practiced severe austerities for twelve thousand years by the calculation of the demigods. During that time, your mind was always absorbed in Me. When you were executing devotional service and always thinking of Me within your heart, I was very much pleased with you. O sinless mother, your heart is therefore always pure. At that time also I appeared before you in this form just to fulfill your desire, and I asked you to ask whatever you desired. At that time you wished to have Me born as your son. Although you saw Me personally, instead of asking for your complete liberation from material bondage, under the influence of My energy you asked Me to become your son."

Sri Isopanisad

The four ages of earth (Satya, Tretā, Dvāpara and Kali) last only twelve thousand years according to the time scale of the upper planets.

Sri Isopanisad 14, Purport:

All the material planets—upper, lower and intermediate, including the sun, moon and Venus—are scattered throughout the universe. These planets exist only during the lifetime of Brahmā. Some lower planets, however, are vanquished after the end of one day of Brahmā and are again created during the next day of Brahmā. On the upper planets, time is calculated differently. One of our years is equal to only twenty-four hours, or one day and night, on many of the upper planets. The four ages of earth (Satya, Tretā, Dvāpara and Kali) last only twelve thousand years according to the time scale of the upper planets. Such a length of time multiplied by one thousand constitutes one day of Brahmā, and one night of Brahmā is the same. Such days and nights accumulate into months and years, and Brahmā lives for one hundred such years. At the end of Brahmā's life, the complete universal manifestation is vanquished.
