A measure of time defined as consisting of one hundred twenty tatkṣaṇas. Sixty kṣaṇas make one lava (defined as a thirtieth part of a muhūrta), which means that the duration of one kṣaṇa is 1.6 seconds. In the Abhidharmakośa (III 88), Vasubandhu defines the terms kṣaṇa and tatkṣaṇa inversely, stating that one hundred twenty kṣaṇas make one tatkṣaṇa.

A unit of time; ten kṣaṇas equals one muhūrta.
