What day will it be 590.57 weeks after October 11, 2004?

Hello loringjustice,

I apologize for the confusion in my comments below over the difference
between your two questions.

My previous answer is a guide to answering the current question.

The answer this time is February 4 or 5, 2016, again depending on what
time on October 11, 2004 you start from.

Here too, one can use the Julian date calculator at:

"Julian Date Converter"
U.S. Naval Observatory: Astronomical Applications Department
http://aa.usno.navy.mil/data/docs/JulianDate.html

590.7 weeks, times 7 days per week, equals 4133.99 days.  

00:00:00 (12:00:00 AM) on October 11, 2004 is Julian date 2453289.5. 
4133.99 days from that time is Julian date 2457423.49, which is February 4,
2016 at 23:45:36 (11:45:36 PM).

23:59:59 (11:59:59 PM) on October 11, 2004 is Julian date
2453290.49999.  4133.99 days from that time is Julian date
2457424.48999, which is February 5, 2016 at 23:45:35 (11:45:35 PM).

As with the previous answer, one can calculate at what times on
October 11, 2004 it would be 590.57 weeks to February 4, 2016, and at
what times it would be 590.57 weeks to February 5, 2016:

00:00:00 (12:00:00 AM) on February 5, 2016 is Julian date 2457423.5. 
4133.99 days earlier is Julian date 2453289.51, which is October 11,
2004 at 00:14:24 (12:14:24 AM).  Thus, on October 11, 2004 before
12:14:24 AM, 590.57 weeks later would be February 4, 2016 (in other words,
prior to 12:00:00 AM on February 5, 2016).  On October 11, 2004 from
12:14:24 AM forward, 590.57 weeks later would be February 5, 2016.

This site is very useful for this type of question:
http://www.timeanddate.com/date/dateadd.html

590.57weeks*7days/week = 4134days (It's actually 4133.99, but I assume
you wanted it rounded.  If not, subtract one day from the answer.)

Plugging that in to the nifty date calculator above gives:
Friday, February 5, 2016

Hope this helps.

I have posted an answer to the previous listing of this question at:

I just realized that the current question says "weeks," while the
previous one says "days."  So this question remains unanswered.  I
will endeavor to answer it now.
