In the first 3 months of a leap year, there are 91 days. 31 + 29 + 31 = 91
92 or 91 or 90 depending on what 3 months and if its a leap year
91.3125 (leap year taken into account)
February is the shortest even on leap years. It's 2 or 3 days shorter, but only 1 in a leap year. The other months all have 30 or 31 days. February has 28 (but 29 in a leap year.)
Providing there is no leap year in that period of days, it is equal to exactly 3 years.
Leap year 3/30 Non leap year 3/31
Anywhere between 3 and 5. It depends on what day of the week Jan. 1 is, and whether or not it is a Leap Year.
Both. It's lunar, with leap-months every 2-3 years to keep in step with the solar seasons.
2 months or 2 months and a day (average month is 30.4 days) * * * * * Or 2 months exactly: Dec+Jan or Jul+Aug Or 2 months + 3 days: Jan+Feb in a non-leap year
5,113 days. 1997 was not a leap year, so it had 365 days. 1998 was not a leap year, so it had 365 days. 1999 was not a leap year, so it had 365 days. 2000 was a leap year, so it had 366 days. 2001 was not a leap year, so it had 365 days. 2002 was not a leap year, so it had 365 days. 2003 was not a leap year, so it had 365 days. 2004 was a leap year, so it had 366 days. 2005 was not a leap year, so it had 365 days. 2006 was not a leap year, so it had 365 days. 2007 was not a leap year, so it had 365 days. 2008 was a leap year, so it had 366 days. 2009 was not a leap year, so it had 365 days. 2010 was not a leap year, so it had 365 days. This gives us 11 non-leap years, or 11 years with 365 days, which is 11(365), and 3 leap years, or 3 years with 366 days. This is 3(366). So the number of days in 1997 - 2010 would be represented by the expression 11(365) + 3(366), which gives us 5,113 days.
3 years 2 months and 3 days (from Jan - Dec and no leap years)
That really depends on which 8 months are being counted. Some months have more days than others, and in a leap year there may well be an extra day. But, as there are 365 days in the average year, and as you're period is three days short of 9 months we could go for 3/4 of a year = 274 and then subtract 3..... to get 271 days.
