Here is an exmaple:

subtract-days.ts:

export function subtractDays(days: number, fromDate: Date = new Date()): Date {
    return new Date(fromDate.getTime() - (days * 24 * 60 * 60 * 1000));
}

And in your angular component import the function and:

your-component.component.ts:

yourOldDate: Date = subtractDays(90);

This is reference for angular/typescript.

To subtract a date from current date time, first need to get the time and then it needs to subtract the time difference you want it.

Example : if you need 90 days difference from current date

currentDate:Date = new Date();
currentDateTime = this.currentDate.getTime();
date = this.currentDateTime - (90 * 24 * 60 * 60 * 1000);
oldDate:Date = new Date(this.date);
