+# Working Hours
+
+A small projects built in as many languages as possible.
+
+## The Idea
+
+The whole idea of this project is to build a command line tool that:
+
+- Receive at least the starting time the person started working;
+- Get the time they went to lunch; as it is optional, it should be considered
+	"12:00" if the user doesn't make this input;
+- Get the time they returned from lunch; as it is option, it should be
+	considered "13:00" if the user doesn't make this input.
+
+The result would be showing how long the user still have to work to complete
+their daily working hours (or if they are doing extra time).
+
+For the total hours a person should work in the day, we'll consider 08:48 (or
+8.8h, or 528 minutes).
+
+## Examples
+
+At 09:00
+
+```
+$ wc 08:00
+So far, you worked 01:00
+You still need to work 07:48
+You still need to work till 17:48
+```
+
+Reasoning: By starting at 08:00, up to 12:00, the user would've worked 4
+hours; going back to work at 13:00, they would still need to work 4h48m, till
+17:48.
+
+At 18:00
+
+```
+$ wc 08:00 12:00 13:00
+So far, you worked, 09:00.
+You did 00:12 hours of extra work.
+You could've left at 17:48
