Jīmūtavāhana (c. 12th century) was an Indian Sanskrit scholar and writer of legal and religious treatises on Vaishnavism of early medieval period.
His Kalaviveka is an exhaustive analysis of the auspicious kala (timings) for the performance of religious rites and ceremonies.
The text is divided into five sections, Vyvaharamukha, Bhashapada, Uttarapada, Kriyapada and Nirnayapada.
This treatise differs in some aspects from Mitakshara, which was prevalent in other parts of India based on Yajnavalkya Smrti.
