Let's ignore the fact that "2004" is written on every page of the calendar, and that the beginning and end of daylight's savings time and other notable dates you might have printed on the calendar will be different.
There are two issues involved here. One of them is leap year, so recycling 2004's arrangement of months, dates, and days of the week will only be possible on another leap year.
The other issue is that a 365 day year advances the same date on the calendar one day of the week. A 366 day year (a leap year) advances it two. In other words, if your birthday is on a Monday this year, it will be on a Tuesday next year, unless there's a February 29 between now and then, in which case it will be on a Wednesday.
You want a leap year where the day of the week is advanced 7 days (also known as zero days, since you're starting over once you cycle through the days).
This is one of those problems where a spreadsheet is going to be more useful than a formula:
2004 = 0 leap year
2005 = 1
2006 = 2
2007 = 3
2008 = 5 leap year
2009 = 6
2010 = 7
2011 = 1
2012 = 3 leap year
2013 = 4
2014 = 5
2015 = 6
2016 = 1 leap year
2017 = 2
2018 = 3
2019 = 4
2020 = 6 leap year
2021 = 7
2022 = 1
2023 = 2
2024 = 4 leap year
2025 = 5
2026 = 6
2027 = 7
2028 = 2 leap year
2029 = 3
2030 = 4
2031 = 5
2032 = 7 leap year

2032.
I have a chart that shows this, going forward through 2050 and all the calandars back through 1800 or so. I'm not sure of any mathematical formula.
The 2004 doesn't come up very often...I'm guessing because of leap year issues...but not really sure.

Calendars recycle every thirteen or fourteen years But, since time moves in one direction-it always increases- you can never reuse any calendar. It will never be 2004 again. It's 2007, so you will always be off by a few decades.

After 2032, when can you use it again? Maybe you can find a pattern from there.

Dude. Just buy a new calendar. Actually, go to the cleaners. They give them away free.
