why do people celebreate valentine day?

valentine day is for celebration of love, thats why people celebrtae that, as few says that why we need this single day to celebrate love as there are 365 days in a year, cant we love taht time, wht this velentine, so i would say on this is, ofcourse there are 365 days in a year to celebrate love, but keep all memories sweet and and lovely we celebrate this day, when we remeber our every velentine that make feel better and happier, all what we want to live?

maybe bec. to show their love to one another...

there is no need to celebrate the valatines day.There should no reason.For time pass only they can celebrate
