Example:
>> datestr(737255)
ans = 14-Jul-2018 # Could just change the '14' to '01' here, but...
>> foo = datevec(737255)
foo =
2018 7 14 0 0 0
>> foo(3) = 1 # This is easier
foo =
2018 7 1 0 0 0
>> datenum(foo)
ans = 737242
>> datestr(foo)
ans = 01-Jul-2018
>> [N, S] = weekday(datenum(foo))
N = 1
S = Sun
