To enter Birthdays select Students from the main menu. Change your classroom or enrollment period as necessary by selecting the Change button next to each. Alternately, you could select All Students using the Change button next to the classroom name. Next, select a student from the list on the left side. In the Student Profile select the "edit icon" on the right side (looks like a piece of paper with a pencil) . You should now be able to change the student's name, gender, birthday and enter a comment.
