Here is an excerpt of the ideology of psycho Hindu extremists. Perhaps one of the most pathetic/hilarious things in the world (Along with tons of other Hindu myths):
Calculating the elapsed time since Brahmas' Creation (LOL WTF) 
432000 × 10 × 1000 × 2 = 8.64 billion years (2 Kalpa (day and night))
8.64 × 109 × 30 × 12 = 3.1104 Trillion Years (1 year of Brahma)
3.1104 × 1012 × 50 = 155.52 trillion years (50 years of Brahma)
(6 × 71 × 4320000) + 7 × 1.728 × 10^6 = 1852416000 years elapsed in first six Manvataras, and Sandhi Kalas in the current
Kalpa
27 × 4320000 = 116640000 years elapsed in first 27 Mahayugas of the current Manvantara
1.728 × 10^6 + 1.296 × 10^6 + 864000 = 3888000 years elapsed in current Mahayuga
3102 + 2017 = 5119 years elapsed in current Kaliyuga.
So the total time elapsed since current Brahma is
155520000000000 + 1852416000 + 116640000 + 3888000 + 5119 =
155,521,972,949,120 years
(one hundred fifty-five trillion, five hundred twenty-one billion, nine hundred seventy-two million, nine hundred forty-nine thousand, one hundred twenty years) as of 2018 AD
Total age of Brahma is 100 (Brahma Years) which is equal to
311,040,000,000,000 Human years
The current Kali Yuga began at midnight 17 February / 18 February in 3102 BCE in the
proleptic Julian calendar. As per the information above about Yuga periods, only 5,120 years are passed out of 432,000 years of current Kali Yuga, and hence another 426,880 years are left to complete this 28th Kali Yuga of Vaivaswatha Manvantara.
