Taking into account the Gregorian leap year rules there are
146,097 days in 400 years
the calendar repeats itself only after 400 years
2000 / 400 = 5 repetitions evenly
that's 146,097 days x 5 repetitions = 730,485 days in 2000 years
there are 86,400 seconds in a day hence
730,485 days x 86,400 sec/day = 63,113,904,000 seconds in 2000 years
