+Task #1: Days Together
+
+    Two friends, Foo and Bar gone on holidays seperately to the same
+    city. You are given their schedule i.e. start date and end date.
+
+    To keep the task simple, the date is in the form 'DD-MM' and all
+    dates belong to the  same calendar year i.e. between '01-01' and
+    '31-12'.
+
+    Also the year is non-leap year and both dates are inclusive.
