Excuse me, a math problem, August 8, 2009 is Saturday, and what day is 20 10? Explain every step of the formula! Explain in detail in gold coins!
Number of days in two-day period (20 10 is not 365 days in leap year, and the rest are 3 1-8 in August and 30 in September, 10/0 days):
365+31-8+30+1= 419 (days)
7 days per week, total weeks and days less than weeks (remaining):
4 19÷7=59……6
Saturday is Friday in six days.
