Agree with @incNick Code, But that should we wrapped inside Pipe. You can create Angular pipe filter like this.
import { Pipe, PipeTransform } from '@angular/core';
@Pipe({
name: 'birthdayFilter',
pure: false
})
export class FilterPipe implements PipeTransform {
transform(items: any, args: any): any {
return items.filter(item => this.isBirthdayInaWeek(item.birthday));
}
isBirthdayInaWeek(birthday){
let weekSec = 7 * 24 * 60 * 60 * 1000;
let today = new Date();
let birthday = new Date(birthday);
birthday.setFullYear(today.getFullYear());
if (birthday.getTime() < today.getTime() && birthday.getTime() + weekSec > today.getTime()) {
return true;
} else {
return false;
}
}
}
Template:
<nb-list-item *ngFor="let yuvak of yuvaklist | birthdayFilter ">
{{yuvak.dateofbirth}}
{{yuvak.firstname}} + + {{yuvak.lastname}}
</nb-list-item>

You need to convert to valid format, like this. var from = 'dd/mm/yyyy'.split("/") var f = new Date(from[2], from[1] - 1, from[0])

I converted into valid format. however, it still return false. isBirthdayInaWeek(dateofbirth) { let weekSec = 7 * 24 * 60 * 60 * 1000; let today = new Date(); let dateParts = dateofbirth.split("/"); let newbirthday = new Date(dateParts[2], dateParts[1] - 1, dateParts[0]); newbirthday.setFullYear(today.getFullYear()); if ( newbirthday.getTime() <= today.getTime() || newbirthday.getTime() + weekSec >= today.getTime() ) { console.log(true); return true; } else { console.log(false); return false; } }

here i put OR(||) condition instead of AND(&&). it shows me all the data. I guess something is wrong with getTime() method. Maybe it is not suited in my case.
