what aarti song is sung everyday in the evening

In Jainism there isn’t a single universal “evening aarti” that is sung by all Jains. Practices vary by temple and community.

What is common:

• Mangal Divo Arti (arti of the lamp) is a popular Jain devotional song performed during rituals that involve lighting a lamp. It is often sung in temples and homes as part of the evening or ritual aarti. ( jainknowledge.com)
• Aarti in Jainism generally means a devotional song sung while offering light to the Tirthankaras and other enlightened beings; it symbolizes dispelling ignorance with knowledge. There are several Jain aarti variants (Arihant Aarti, Jin Aarti, Mahavir Swami ki Aarti, etc.) that may be sung depending on the practice of the place. ( jainknowledge.com)

Simple meaning (arth) of the practice:

• The lamp represents knowledge; lighting it removes darkness (ignorance).
• The singing of aarti expresses reverence to the Tirthankaras and a wish to follow their path.
