Yes, you can arrange your daughter’s marriage on Panguni Uthiram -April 1, 2026, as it is considered very auspicious in our tradition.
This day is sacred because it marks the divine marriages of Lord Shiva and Parvati, Lord Muruga and Deivanai, and even Lord Mahavishnu with Andal (as per Srivaishnava sampradayam). So naturally, it’s seen as a highly favorable day for conducting marriages, upanayanams, and other samskaras.
Just check the exact Uthiram nakshatram timings and the lagna (muhurtham) for that day with a good panchangam or local astrologer, especially if you follow a specific panchangam (like Pambu Panchangam, Thirukkanitha, etc.).
Nakshatram and thithi should be properly aligned during the actual muhurtham time. Also ensure there's no dosham like Rahu Kalam, Yamagandam, or Durmuhurtham during the time you're planning.
So short answer: Yes, Panguni Uthiram is a great choice for marriage. Just finalize the lagna muhurtham with proper panchangam consultation.
If you want, share your daughter's nakshatram and birth time, and I can help check a good time for that day.
