Mate, go through foretelling of Niamat Allah Shah wali and you will be able to pin-point down to a month when you'd expect this war. Every single prediction he made has came true already. In our time, we are witnessing Shah Shair-e-Ali.
Arrival of Shah Shair-eAli
A leader will appear in Pakistan, who will be master of two fronts. He would lead the country out of troubles and make a military alliance with a country in its north. In my understanding, Gen. Raheel is that and Pakistan is about to form a military alliance with China. So this prediction has just came true.

Star of a low intensity war
Watch this video where analysts are talking Indian's plan to do a limited "Kargil" with Pakistan. If it is true, such an action would take roughly 6-12 months of preparedness on part of India. Now look at this prediction from Niamat Allah Shah Wali.
"A low intensity fight will begin between India and Pakistan in the areas around Gilgit Baltistan between two Eids. To counter that, China too will start a low intensity war in the area of Tibbet".
We just had Eid ul Idha and next Eid is 9+ months ahead. If India has decided to do a limited Kargil, logically, we can expect it to be happening around or after Eid next year. So that prediction is inline with our reality.
The start of main war - Ghazwatul Hind
Niamat Allah Shah Wali says, low intensity war will begin between two Eids. India will be unsuccessful in getting anything out of it and in frustration, launch a full scale war -
the Ghazwatul Hind. That battle is full intensity Nuclear War with massive causalities on both sides. There is a little confusion in translation weather Niamat Allah Shah Wali has said 6 months or 6 years but it is going to be decisive and India's last - with Pakistan coming out victorious and Hindu leader getting arrested and brought in chains.
One final bit has yet to come true
Niamat Allah Wali said when Pakistan will make militry allience with China, an un-restricted unmeasured flow of militry assets will happen from China to Pakistan. This is the missing bit and I am waitin this to happen. Since Pakistan and China are already undergoing a defence pact, you can easily see this would happen within next few months.
All this said with my limited knowledge and Allah knows the best.
