# count Saturday and Sunday in a range of dates with datapicker

1

How can I know when Saturdays and Sundays are in a range of dates? 01-01-2017 & 01-20-2017 (for example), knowing that datapicker (bootstrap) has a

taking arrangement = > Sunday [0] [Monday [1] Tuesday [2] Wednesday [3] Thursday [4] Friday [5] Saturday [6]

Here is a solution:

``````function cuentaFindes(){
var inicio = new Date("2017-02-24"); //Fecha inicial
var fin = new Date("2017-03-10"); //Fecha final
var timeDiff = Math.abs(fin.getTime() - inicio.getTime());
var diffDays = Math.ceil(timeDiff / (1000 * 3600 * 24)); //Días entre las dos fechas
var cuentaFinde = 0; //Número de Sábados y Domingos
var array = new Array(diffDays);

for (var i=0; i < diffDays; i++)
{
//0 => Domingo - 6 => Sábado
if (inicio.getDay() == 0 || inicio.getDay() == 6) {
cuentaFinde++;
}
inicio.setDate(inicio.getDate() + 1);
}

return cuentaFinde;
}
``````

This I think would be what you are looking for:

Remember that the week counts from 0; Sunday = 0 and Saturday = 6

``````function contadorSabadosYDomingos(fechaInicial,fechaFinal){
fechaInicial = fechaInicial.split("-");
fechaFinal = fechaFinal.split("-");

var dtInicial = new Date(fechaInicial[2], fechaInicial[1] - 1, fechaInicial[0]);
var dtFinal =new Date(fechaFinal[2], fechaFinal[1] - 1, fechaFinal[0]);

while(dtInicial <=dtFinal){
if(dtInicial.getDay()===0||dtInicial.getDay()===6){
}
dtInicial = new Date(dtInicial.getTime()+86400000);// se agrega un dia

}
}
``````

Another solution would be to assign a variable to the starting date, do a repeat cycle where you will add a day to that variable and you will be asking if the date is Saturday, if so you add a + 1 to the counter, the cycle ends when the date you are adding one day reaches the end date. You would have something like that in C #, you would have to spend it no more

``````public int DiasSabados(DateTime inicio, DateTime fin)
{
while (inicio < fin)
{
if ( inicio.DayOfWeek == DayOfWeek.Saturday)
{
}
}
}
``````

JavaScript

``````while(inicio < fin)
{
if (inicio.getDay() == saturday)
{
