Calculate the number of complete years from 1900 to 1904:

Years 1900, 1901, 1902, and 1903 need to be counted.

Check for leap years:

• 1900: Not a leap year (divisible by 100 but not by 400) → 365 days
• 1901: Not a leap year → 365 days
• 1902: Not a leap year → 365 days
• 1903: Not a leap year → 365 days

Total days in complete years $= 365 \times 4 = 1460$=365×4=1460 days

Days from January 1, 1904 to January 4, 1904:

Number of days $= 3$=3 days

Total days from January 1, 1900 to January 4, 1904:

$= 1460 + 3 = 1463$=1460+3=1463 days

To find the day of the week, divide by 7:

$1463 \div 7 = 209$1463÷7=209 with remainder $0$0

Since the remainder is 0, January 4, 1904 falls on the same day as January 1, 1900.

Therefore, January 4, 1904 was a Monday.

The answer is Option 2: Monday.
