# How many days are there from 5th January 1995 to 18th march, 1995?(a) 8(b) 73(c) 63(d) 78  Hint: January has 31 days, February has 28 days and March has 31 days in their respective months. Start counting from 5th January till 31st January and then count total days in February and in the last count from 1st March to 18th March. Finally, add the three values.

A month is a unit of time, used with calendars, which is approximately as long as a natural period, related to the motion of the Moon. There are 12 months in a year. Some months have 31 days, some have 30 days and February has 28 days only. If the year is a leap year then February has 29 days. When we add the total number of days in a year it turns out to be a total of 365 days in a non leap year and 366 days in a leap year. A leap year is a calendar year that contains an additional day. A simple way to know whether a year is a leap year or not is that we divide the given year by 400, if the remainder is 0 then the year is leap year, otherwise non leap year.
Now, we have the year 1995, which is not divisible by 400, therefore it is a non leap year. This year February has 28 days. Now, we start our count from 5th January, we get that, upto 31st January the total number of days are 27. Then we have to include all the 28 days of February. Now, from 1st march to 18th march there will be a total of 18 days.
Therefore, the total number of days are 27+28+18=73.
Hence, option (b) is the correct answer.

Note: Don’t just subtract 5 from 31 to get the number of days in January as the result would be 26 and finally we will get the wrong answer. We have to include the day of 5th January also, so, there will be a total of 27 days in January.
