Time of Intention (NIYAH)

The intention is made on the night before the rise of fajr and for every night of fasting in the whole month. The evidence for this is the hadeeth of Hafsah.

“Whoever does not determine to fast before fajr will have no fast (i.e. it won’t be accepted)." (Ahmad, an Nasaaee, at Tirmidhi, Abu Daud, ibn Majah, and ibn Hibban eho classified it as saheeh – authentic)
