毗舍波耶那说：“尤提士提罗，依月历而论，温和的摩伽月已然到来。这是它的白半月：一分已过，尚余三分。”

The verse foregrounds dharmic attention to kāla (proper time): auspicious actions, vows, gifts, and observances are traditionally aligned with the lunar calendar, and the narrator marks the season and fortnight to situate what follows within an appropriate ritual-ethical context.
Vaiśampāyana informs Yudhiṣṭhira that the lunar month Māgha has begun and that the bright fortnight is underway, with most of it still remaining—setting the temporal scene for subsequent instructions or observances in the discourse.
