+83 Lucy was born on Wednesday, December 1st, 2004. That Wednesday was the first day of her life. Her parents held a party for her on the $1000$th day of her life. On which day of the week was the party?
+2440 Mr. BB, You forgot the sage advice I’ve offered to you many times: You have to be smarter than the machine you are using. The machine gave you an answer and you believe it –it must be true!
The machine is correct, so it is smart. The information you gave to the machine is not correct, so you are not smarter than the machine.
The question clearly indicates. That Wednesday, December 1st, 2004 was the first day of Lucy’s life. So … adding a thousand days to this would give the 1001st day.
This type of question is normally solved using modulo arithmetic: 999 mod 7 = 5. If Wednesday is the first day then Monday is the fifth day.
I bet you are wondering why it’s 999 mod 7 instead of 1000 mod 7. I can answer your question, but I’ll let you figure it out –you really need the practice!

+36916 2004 was a leap year
1000 days later will not hit another leap year (which come every 4th year)
day 1 was a Wednesday ... 999 days later would be 142.71 weeks
day 1 8 15 22 are all wednesdays
day 1 + 142*7 = 995 is a wednesday 999 would be a Sunday , I believe
+2440 Leap year days are irrelevant here.
The question asks on what day of the week the celebration will occur after 1000 elapsed days, where first day is the day of her birth. If she was born on a Wednesday then the celebration will occur on a Monday, no matter what year or date she was born.
+36916 Yep...... You are correct ....(at least I found the same answer) 1 day later would be thursday day two of her life
7days later would be wdnesday again day 8 of her life
994 days later would be a wednesday day 995 of her life
995 days later = thursday day 996 of her life
996= friday
997 = sat
998 = sunday
999 = MONDAY day 1000 of her life
THANX , Guest !
