Sandhyavandanam literally means "salutation to Sandhya".
Sandhya, in turn, has traditionally been interpreted either as "the transition moments of the day" (namely the two twilights dawn and dusk), or as "the solar noon".

This is a religious ritual performed which consists of recitation from the Vedas.
These rituals are performed three times a day -
at morning (prātaḥsaṃdhyā),
noon (mādhyāhnika) and
evening (sāyaṃsaṃdhyā).
