my PC shows it is a Sunday..
it makes sense with 1st week starting with a Sunday as the calendar was invented much after.
There was no year zero, so there is no answer to the question if that is what you mean. If you meant 2000, then the 1st of January 2000 was on a Saturday.
what day of the week was January 1st 1936
Its Friday
January 1st 1900 was a Monday.
January 1st 1905 was a Sunday.
1st January 1986 was a Wednesday.
January 1, 1965 fell on a Friday.
January 1, 1900 fell on a Monday.
January 1st, 1978 fell on a Sunday.
Nope... Every date in the calendar eventually falls on every day of the week.
What day of the week was January 5 2005
It is the 22nd of January. The actual day of the week will depend on the year, so it can be any day of the week.
