* Dharmic viswas: Purane samay mein, logon ka maanana tha ki suraj ugalne se pahle ki ghadiyaan "shaapit" hoti hain aur us samay faasi dena "pashchatap" ko lekar theek nahin tha. Isliye faasi subah 4 bhej ke baad, suraj nikalne se pahle di jaati thi.
* Aatma ke swarga jane ka viswas: Kuchh dharmic vichar dharaon ka maanana tha ki suraj nikalte samay aatma swarg chali jaati hai. Isliye faasi subah 4 bhej ke baad, suraj nikalne se pahle di jaati thi, taaki aatma ko "swarg" jane ka mauka mil sake.
* Prashasanik suvidha: Purane samay mein prashasanik suvidhaon ka abhav tha. Isliye faasi din ke samay dene se logon mein bheed lag sakti thi aur kanoon vyavastha mein bhang ho sakti thi. Subah 4 bhej ke baad, suraj nikalne se pahle faasi dene se yeh problem samasya ka hal ho jaati thi.
* Mansik dard kam karna: Faasi dene ki pratikraiya ko kam karne ke liye, subah 4 bhej ke baad faasi dena ek prakar ka "mansik dard kam karne wala" uptahar tha. Faasi se pahle ki ghadiyaan aise waqt hoti hain jab log so rahe hote hain aur unki jaagrukta kam hoti hai.
Aajkal, yeh riwayat bahut purani ho chuki hai aur yeh prakat nahi hai ki aise kyon kiya jaata hai. Iske peeche ke reason, jinka humne upar jaan kaari ki, purane samay ke dharmic aur samayik vichar dharaon se jude hain.
