Short answer

• Shvetāmbara (Mūrtipūjak): Do Devāsī Chaityavandan in the daytime and Raī (night) Chaityavandan after sunset on the first seven days. On Samvatsarī (the 8th day), perform the full Samvatsarī Pratikraman; a separate Chaityavandan is not required that evening.
• Shvetāmbara (Sthānakvāsī/Terāpanth): Chaityavandan is not practiced; observe daily Samayik and the prescribed Pratikraman each day, with the full Samvatsarī Pratikraman on Samvatsarī.
• Digambara (during Das Lakshan, which starts the day after Shvetāmbara Samvatsarī): Offer daily Deva-vandana/Chaitya-vandana as per your tradition along with Alocanā–Pratikraman; focus is on the ten virtues.

Simple guidance you can follow

• Days 1–7 of Paryushan (Shvetāmbara Mūrtipūjak):

- Morning/Day: Devāsī Chaityavandan (complete form if possible). - Evening: If you are doing the daily Devāsī/Raī Pratikraman, that suffices; Raī Chaityavandan is optional.

• Samvatsarī day:

- Do the full Samvatsarī Pratikraman with Kṣamāpanā; no separate Chaityavandan is necessary.

• If time is short:

- Do the shorter (laghu) Chaityavandan respectfully rather than skipping it.

• Always include Navkār Mantra with reverence; adding stotras like Logassa and Namutthunam is traditional for Mūrtipūjak. Sthānakvāsī/Terāpanth should keep to their non-mūrti-pūjā liturgy.

This keeps the observance authentic: daily avasyakas throughout Paryushan and full Samvatsarī Pratikraman on the forgiveness day.
