eomday - Last day of month

Syntax

Description

E = eomday(Y, M) returns the last day of the year and month given by corresponding elements of arrays Y and M.

Examples

Show the end of month for January through September for the year 1900:

eomday(1900, 1:9)
ans =
    31    28    31    30    31    30    31    31    30

Find the number of days during that period:

sum(eomday(1900, 1:9))
ans =
   273

Because 1996 is a leap year, the statement eomday(1996,2) returns 29. To show all the leap years in the twentieth century, try:

y = 1900:1999;
E = eomday(y, 2);
y(find(E == 29))

ans =
  Columns 1 through 6
     1904     1908     1912     1916     1920     1924

  Columns 7 through 12 
     1928     1932     1936     1940     1944     1948

  Columns 13 through 18 
     1952     1956     1960     1964     1968     1972

  Columns 19 through 24 
     1976     1980     1984     1988     1992     1996
