+#Python Dates
+#A date in Python is not a data type of its own, but we can import a module named datetime to work with dates as date objects.
+
+#Example
+#Import the datetime module and display the current date:
+
+import datetime
+
+x = datetime.datetime.now()
+print(x.year)
+print(x.strftime("%A"))
+print(x)
+x = datetime.datetime(2020, 5, 17)
+#The datetime() class also takes parameters for time and timezone (hour, minute, second, microsecond, tzone)
+#but they are optional, and has a default value of 0, (None for timezone).
