BirthdayMatrix application celebrates a birthday of the user or one of the user's friend provided that the age is 22 years or more. For that sake, the user chooses a birthday date. Then, the user selects one of nine frames to enclose a 4X4 number matrix. The user may also write down the user's name or the name of the celebrating person. After a short while, the application presents a GIF (graphics Interchange Format) associated with a celebrated birthday. The GIF includes a square within a decorated frame, and a 4X4 super-magic square having the birth month as the number on the upper left corner of the square. The super magic square has a sum which equals the celebrated age. For short time durations, alternating number quartets having the above age as a sum are emphasized by a yellow background. The name associated with the celebrated birthday appears on top of the framed square. By pressing a "share" button, the user shares the GIF with a WhatsApp account, a facebook account or elsewhere.
