Did 2010 have the same calendar as 2004 - seeing as both years ended on the same weekday?

No. 2004 was a leap year, but 2010 was not.

When was the last calendar equal to 2012?
Because of the extra weekday each year, and because of leap years, identical non-leap year calendars repeat on a cycle of 6 or 11 years. Leap years repeat every 28 years. (There are only 14 different possible calendars.) The years that were the same calendar as 2012 were 1984, 1956, and 1928.
Why is the leap day always one weekday later after twelve years - as in 2000 it was Tuesday and in 2012 it was Wednesday?
The length of most 12-year periods is 626 weeks and one day. It's that one day that puts a certain date on the subsequent weekday after twelve years, just as a certain date is on the subsequent weekday after one regular year, the length of which is 52 weeks and one day. (If there's a leap year day during the intervening year, the date will fall a weekday later.) 12-year periods that include the year 2100 will be exactly 626 weeks long, since 2100 is not a leap year, so the weekday will be the same after a twelve-year period that includes 2100. (2100 will be only the fourth year that is different from the Julian calendar since the world started switching to the Gregorian calendar in 1582; the other years that were different were 1700, 1800 and 1900.)
Will a 2008 calendar repeat itself in 2013 - since both years start on the same weekday?
Only until February 28. The next day on the 2008 calendar is February 29, but the next day on the 2013 calendar is March 1. The most recent year that matches 2013 is 2002. Coincidentally, Easter falls on the same date in 2002 and 2013 as well.
Why do people keep saying the world will end on the 21th of December?
There was once an ancient civilization called the Mayan civilization unlike our own. Their calendar went on for years and years, until the day the calendar ended. On December 21st, 2012, the world is supposedly going to end because the Mayan calendar ends on that day.
How do you know what day of the week was October 13 1972?
One way that I determine the weekday of a particular date is to enter the date into a cell in a Microsoft Excel spreadsheet and to format the cell to show the weekday. For dates before 1 January 1900 I add a multiple of 400 to the year to make the year greater than 1899 (the Gregorian calendar completely repeats itself every 400 years).The other way is to look at the year in the perpetual calendar I created for myself.
Why does a calendar date which fell on Sunday always fall on Wednesday eight years later?
Each of the six regular years advanced the date by one weekday, and each of the two leap years advanced the date by two weekdays. 6 x 1 + 2 x 2 = 10. Ten days after Sunday is Wednesday.
Why does a given calendar date which fell on a Saturday always fall on a Wednesday twenty years later?
Every twenty-year period that begins after the 28th of February 1900 and before the 29th of February 2080 includes five leap year days. Each calendar date advances one weekday for every year plus an additional weekday for every leap year day, because every regular year consists of 52 weeks plus one day, and every leap year consists of 52 weeks plus two days. So for every date during the period specified in the first sentence, the weekday twenty years later will be the 25th weekday after the original date (20 for the number of years plus 5 for the number of leap year days equals 25).For every Saturday after the 29th of February 2080 and before the 1st of March 2100, the weekday twenty years later is Tuesday, because every twenty-year period that begins between those dates includes four leap year days (2100 is not a leap year).
How many weekday in a one year?
262 in leap years that begin on Monday, Tuesday, Wednesday or Thursday 261 in leap years that begin on Sunday or Friday and regular years that begin on any weekday 260 in any year that begins on a Saturday and regular years that begin on Sunday
What was the year 13000 years ago?
Well, as the date changes all the time, soon this will be out of date. But seeing as it is currently the year 2013.AD, the answer to your question is: 7087.BC
What do the Gregorian calendar and Julian calendar have in common?
almost everything... The major difference between the two calendars is the Julian calendar has 100 leap years in every 400 years, and the Gregorian calendar has 97 leap years in every 400 years. That makes the average length of a Julian calendar year 365.25 days and the average length of a Gregorian calendar year 365.2425 days. As a result, it takes only about 128 years for the Julian calendar to accumulate a full day of error, but for the Gregorian calendar to accumulate a full day of error takes about 3200 years.
Why the change from the Julian to the Gregorian calendar?
The Julian calendar looses a day every 128 years. The Gregorian calendar looses a day every 3200 years.
When will the 2008 calendar repeat?
The 2008 calendar will repeat in 2036. Calendar patterns repeat every 28 years because of the cycle of leap years.
