1. ## day of month

first day of 1999 is sunday.what day is the last day?

2. This is pretty simple, there's 365 days in a year. Divide 364 (We already know Sunday) by 7, take the remainder and count from Sunday and you'll have your answer:

$\frac{364}{7} = 52 \ remainder \ 0$

The end of the year is also a Sunday. If it is a leap year, it will be the day after that.

I will give you 2 hints:

(Hint 1)
1999 wasnt a leap year. So it had 365 days. Sunday repeats for every 7 days.... that is if 1st is a sunday, so is 8th Jan, 15th Jan and so on.....

(Hint 2)
365 = 1 + 7 x 52

4. ## any other suggestion

is tat mean the answer is sunday
but they have not given sunday as an option for me
the option they given are
monday,wednesday
friday,saturday

5. I was wrong.

Sorry

6. It's not monday... If you look at any calendar that has many years recorded on it... All years start and end on the same day of the week, unless it is a leap year, then it ends on the day after.

You cannot include a day once it has been considered already. If you see it started on Sunday and count a week after that, you get Sunday:

Sunday...

Monday... 1
Tuesday.. 2
Wednesday... 3
Thursday. 4
Friday..... 5
Saturday. 6
Sunday... 7

If you continue this till the end of the year, you get 364 days.

That means, all years start and end on the same day except on Leap Year.

Oh, you are correct, thank you. The first day of the next year would be a monday. Not the last day of the same year.

8. ## so which is rite

give me a suggestion plz
can i send the ans as monday???

I believe that the first day of the next year would be a Monday, however Aryth was correct every year other than leap years end on the same day.
So if you question asks what day the next year began on then yes, it would be Monday.

10. If the number if days in a year was a multiple of 7, then a given day would land on the same weekday every year because the week and year cycles would be aligned. If the year was 7 days long, what would the 8th day be? If they were 14 days long, what would the 15th day land on? The same as the first day, right?

However,

365/7 = 52 and 1/7th (i.e. one day longer than 52 weeks)

366/7 = 52 and 2/7ths (i.e. two days longer than 52 weeks)

So if, say, in a normal 365 day year, the first day was Tuesday...

The first 52 weeks would be

[Tue,Wed,Thu,Fri,Sat,Sun,Mon]

Then the spare day at the end of the year would be a Tuesday.

Making the first day of the next year a Wednesday

If it were a leap year, then you would have 2 spare days after the 52 - Tuesday and Wednesday, making the first day of the next year a Thursday.

11. And of course, we know that the actual 1st day of 1999 was on a Friday.

but i told they have not given sunday as an option

15. There's something wrong with the question, then, because all leap years land on years that are multiples of 4.
