The term "Kalyan Mandir" in Jainism generally refers to a temple or place of worship dedicated to Jain Tirthankaras or deities. However, there are multiple temples with the name "Kalyan Mandir" in different regions, and no specific, universally-recognized "Kalyan Mandir" is mentioned in the core Jain scriptures or traditional historical records as a singular, significant temple.

If you are referring to a specific Kalyan Mandir in a particular city or region, please provide more details. Otherwise, Jainism as a tradition has a long history of temple building, but the construction dates of individual temples named "Kalyan Mandir" would depend on their specific locality and historical record.

If you have a particular Kalyan Mandir in mind (for example, in Kalyan city, Maharashtra, or any other location), please specify, and I can try to provide more information related to Jainism and that temple.
