Setting up a calendar template is not too difficult, and once set, can require as little as entering a single date to populate the whole calendar.
A more detailed response would depend on a clarification of 'do a check in/out day by day of my employee.'
How do you want to record/indicate the 'check in/out'? How will the check in/out fit into the underlying calendar?
A screen shot of a mock-up table would probably best convey your ideas.
