Why do people in jonas's community have the same birthday?
alexira [117]
Everyone was not born in the same day but they do not celebrate birthdays like us.  Every year they move the class of children who were born in the same year up together.  This means that all of the babies who are recognized as Ones will be recognized as Twos together, and then Threes in another year.

Since the babies are not all the same age biologically, some kids have an advantage. 

Some were already walking, wobbly on their unsteady legs; others were no more than a few days old, wrapped in blankets, held by their Nurturers. (ch 2, p. 11)

Although it is claimed that the differences disappear by the time they are school age, there might be some advantage to being an older One versus a younger One.  Jonas was a little bit older, and he notes that it had given him a “slight advantage” when he was younger (ch 7, p. 50).  Since he is more sensitive and mature than the others, perhaps the advantage was not slight or temporary.

There are fifty children born each year.  They are given numbers from 1 to 50.  Their parents refer to them by number and not by name whenever they are frustrated with them, kind of like how our parents call their children by their full names.

Sometimes parents used them in irritation at a child's misbehavior, indicating that mischief made one unworthy of a name. (ch 7, p. 50)

For this reason, kids may not like hearing their numbers.  However, having a number is just part of their lives.  Since they are taught from a young age to not value individuality, it would not concern them to have a number.

The use of numbers and the abandonment of birthdays were both attempts by the community to institute Sameness.  This way, no one is singled out.  No one person is celebrated, except when the Ceremony of Twelve gives them assignments.  Everyone works for the good of the community, and the self is unimportant.

xxMikexx [17]

<em>The provided nerdluv.php has a header/footer and links to singup.php and matches.php. This file's contents are complete, but larger parts of it are repeated on other pages. The repeated parts should be turned into functions in common.php that are called by each page. The sign up link leads to singup.php and check matches to matches.php.</em>

<em>The signup.php page has a header logo, a form to create a new acount, and footer notes/images. You must write the HTML code for the form, the form should contain the labeled fields such as name, gender, age, personality tipe, favorite OS, seeking age, and sign up.</em>

<em>The signup-submit.php code should creat a line representing the new user's information and add it to the end of the file. The resulting page has the usual header and footer and text thanking the user. The text log in to see your matches links to matches.php.</em>

<em>Use functions, parameters/return, included files/code, loops, variables, etc, to avoid redundancy. If you have HTML or PHP code that is shared or redundant between multiple pages, place it into functions in common.php. You can include your common.php in your other pages.</em>
