Chauvihar ka samay raat ko local sunset ke baad shuru hota hai aur subah ke sunrise par khatam hota hai. Matlab:

• Chauvihar: sunset ke baad se sunrise tak kuch bhi nahi khaya-piya jaata (na khana, na paani).
• Tivihar (agar aap chahen): raat me sirf paani diya ja sakta hai aur khana nahi; sunrise ke baad paani/khana chal jaata hai,Tradition ke anusar pachchakkhān ke hisaab se alag-alag hota hai.

Aaj ke liye iska matlab hai: aapki jagah ke local sunset ke samay se shuru hoga aur sunrise par khatam hoga. Aapko aaj ki sunset time dekh kar last sip/khana sunset se pehle le lena chahiye, aur subah sunrise ke baad paani ya bhojan shuru karna chahiye (apne tradition ke pachchakkhān ke hisaab se).

Aur padhe-likhe ke liye:

• Chauvihar ki vyakhya aur sambhav pachchakkhān ki jaankari yahan milegi.
• Chauvihar water timing ki vyakhya aur niyam yahan milenge.

Note: Yahan diya gaya samay general hai; apni jagah ke sunset/sunrise ke exact times dekh kar hi final karen.
