The mentioned year that is used to calculate the age by Ahmadies on their site

On the subject of the date of his birth, the Promised Messiah(as) writes in his book ‘Tohfa Ghowladiyya’ that he was born on Friday 14th of the Lunar calendar. Further clarifying this, Hadhrat Mufti Mohammad Sadiq(ra), a close companion of the Promised Messiah(as), relates to us in his book ‘Dhikr-e-Habib’ (Seerah of the Life of the Promised Messiah (as) ), that the Promised Messiah(as) said that he was born, using the lunar calendar, on Friday 14th of the month of Phaalgun (Hindi: phaalgun is a month of the Hindi calendar. In India’s national civil calendar, Phaalgun is the twelfth month of the year, beginning on 20 February and ending on 21 March).
Upon further research there appear to be only two occasions upon which the above three common denominators (1.Friday, 2.14th day of a Lunar month, 3.the Indian month of Phaalgun) occurred simultaneously
1. 17th Shubat (February) 1832AD = 14th Ramadhan 1247 AH = 1st Phaalgun 1888
2. 13th Shubat (February) 1835 AD = 14th Shawwal 1250 AH = 1st Phaalgun 1891
The Promised Messiah(as) wrote in his book ‘Haqeeqatul Wahi’ that he received his first revelation from Allah(swt) in the year 1290 AH. Then writing in his book ‘Taryaqul Qulub’ he writes that when he reached the age of 40 years he began to receive revelation. In assessing these two figures we come to the understanding that the Promised Messiah(as) was most likely born in the year 1250AH/1835AD (1290 – 40 = 1250).
The above mentioned years are wrong. The first mentioned year 1832 is not used to calculate, so I left it, but it is also wrong. The second year 1835 as shown below is wrong as well.
The correct year can be verified by his own claim in which there is no room for word play. As shown below.
Things to remember.
1) When he was 40 he started his revelation.
2) He got revelation that he would live to be 80 or near it. So by this, revelation, the time for dawaa is 40 years.
2) Out of which 10 years have passed.
3) The book Nishan-i-Aasmani (The Heavenly Signs), published in 1892.
So to calculate age without jumping through hoops is simple as follows.
He was 40 when got the revelation and book was written in 1892. By this time 10 years have passed.
40 + 10 = 50. So he was born in 1892 -50 = 1842. As shown above in the calendars. Which also satisfy Qadianies set condition and is just proved by Mirza Sahib own writing which is simple and straight.
He died in 1908. So 1908-1842 = 66 years. Which is no way close to be 80. Plus dawaa time which was suppose to be 40 is also not close. 1908-1892 = 16. Remember 10 years already passed so 16+10 = 26. Way off.
So there you go, he is proven liar by his own admission. And liar can't be a prophet or mujaddid.
