Yes, it is a valid tap (external tapa: Anshan). But because you do parna (break) after the first 2 upvaas, it is NOT one continuous 7‑day fast. It counts as two separate fasts:

• 2 continuous upvaas = “Be Upvās” (Skt: Dvi‑upavāsa)
• 5 continuous upvaas = “Pañch Upvās” (Skt: Pañca‑upavāsa)

So, the name is not a single special tap like Atthai (8 continuous), Attham (3 continuous), or Varsitap (alternate‑day for a year). It is simply two Anshan tapas done in two phases during Paryushan.

Tradition notes

• Shwetambar: usually only boiled water in daylight during upvaas; do pachchakkhān (pratyākhyān) for each phase, with proper samayik, pratikraman, and parna maryādā.
• Digambar: often nirjal (no water) unless guided otherwise; likewise, take the vow for each phase and follow maryādā.
