It depends on the amount of leap years during that period. During a period of 7 years there is at least one leap year, and sometimes two. If there were two leap years, it would skip two days, so be 9 days after a Thursday, which is a Saturday. The 1st of January 1998 was a Thursday, and the 1st of January 2005 was a Saturday, because there were two leap years between 1998 and 2005, which were 2000 and 2004. It is not always the case though. The 1st of January 2009 was a Thursday, but the 1st of January 2016 is a Friday, because there is only one leap year between 2009 and 2016, which is 2012.
January 10th
After 2010, the next time, it falls on Thursday is January 2016.
Not always what you might expect, it ranges between 104 and 106 depending on if it is a leap year and the date of the first Saturday in January. For normal years if Saturday falls on the 1st or 7th January there are 105, on leap years if Saturday falls on the 1st January there are 106 and if it falls on the 7 January there are 105. There are 104 at all other times
These are years in which December 31st falls upon a Thursday, or when it is both a Leap Year and December 30th falls upon a Thursday. Or, you could say they are years when January 1st is on a Thursday, or when it is both a leap year and January 2nd falls upon a Thursday. 2015, 2020, 2026, 2032... It will always be 5 or 6 years between each such occurrence.
Thanksgiving always falls on the 4th Thursday of November.
28 January 1965 was a Thursday.
Saturday
In 2010, Thanksgiving falls on November 25 - in the US, Thanksgiving always falls on the forth Thursday of November.
January 16, 2010 falls on a Saturday.
January 25, 2020 falls on a Saturday.
Thursday, May 12th, 2011 falls 120 day after January 12th, 2011.
Not always. For example: January 1st, 1962 was a Monday but January 1st of 2012 was a Sunday. For other part: January 1st, 1955 was a Saturday and January 1st, 2005 was a Saturday too. In general, your 50th birthday falls on the same day of the week of your birth or one day less.
