Answer 15

This question may sound easy, but it is not.

Some reasons for this:

* Since 46BC in the western european history the number of days in a year may vary between 365 and 366, except for the year 1582AD which had 355 days. Since 1583AD the gregorian calender ensures that the average year has 365.2425 days.

* Because of leap seconds, not all days have the same number of seconds.

The International Astronomical Union defines an average year as 31.5576Ms (Mega-seconds) = 365.25 days. (not leap days)

NIST recommends to use 31.536Ms = 365days.

So, using the IAU recommendation, 25a = 788.94Ms.

Using the NIST recommendation: 25a = 788.4Ms.

Using the sidereal year: 25a ~ 788.954Ms.

If you know, which years you are talking about, you can find out the exact number of seconds, of course.

Answer 16

it changes - it depends if the 25 years includes 6 or 7 leap years :P
