No specific Jain kalyanak appears to be listed for today, Saturday, April 25, 2026 in the Jain calendar I checked. The nearby observance in this period is Varshitap Parna / Akhatrij (Akshaya Tritiya), which is a major Jain observance but not a kalyanak. ( jaincenter.org)

If you want, I can also tell you the Jain tithi for today in simple terms.
