567648000+4 days= 567993600 seconds, if there were four leap years in it

Allowing for leap years, there are 6573, 6574 or 6575 days in 18 years. That is equivalent to 567907200, 567993600 or 568080000 seconds respectively. Furthermore, there may be some leap seconds - usually added but occasionally subtracted.

Approx 568036800 seconds. The exact number depends on how many leap years there were in the interval and on whether or not there were any leap seconds.

70 years will include either 17 or 18 leap years, depending upon when one starts the counting. 365 days = 31,536,000 seconds 365 days by 70 = 2,207,520,000 seconds As 1 day = 86,400 seconds then, * If we are looking at 17 leap years, then we need to add 86,400 x 17 = 1,468,800 * If we are looking at 18 leap years, then we need to add 86,400 x 18 = 1,555,200 So, 70 years is either ... * 2,207,520,000 + 1,468,800 = 2,208,988,800 seconds or * 2,207,520,000 + 1,555,200 = 2,209,075,200 seconds
