I get home late from work — how can I keep Pradoṣa vrat and its evening pūjā?

keep a light fast through the day, and do a short Śiva pūjā in the pradoṣa window around sunset — even at a temple near work or with a small liṅga carried with you.

Pradoṣa vrat falls on Trayodaśī of each fortnight, observed on the day when Trayodaśī prevails during pradoṣa kāla, roughly from about 45 minutes before to 45 minutes after sunset. Soma Pradoṣa (on a Monday) and Śani Pradoṣa (on a Saturday) are considered especially auspicious.

For office-goers: eat fruit or a light phalāhāra during the day. Check the pradoṣa time for your city. If you can, step out to a nearby Śiva temple, or keep a small liṅga or picture at your desk or in your bag and offer water, a flower or simply your prayer with “Om Namaḥ Śivāya”. If you reach home only after the window, do the pūjā as soon as you arrive; it is still accepted with devotion.

Finish with the Pradoṣa kathā or Śiva Cālīsā, then eat a simple meal. Thirteen or 26 Pradoṣas are common counts before an udyāpana.

Soma and Śani Pradoṣa are especially valued · Source: Skanda Purāṇa tradition; Nirṇayasindhu
