now i want to calculate the hours and min from two different time
please help me anyone. how can i do that
Thanks in advance

So you have 2 differents formats or it’s a mistake ? You could probably use momentjs to solve it.

two different time is like that start time 10:27 and end time 12.40

it’s a mistake. ok let me try

4

return moment('1027', 'HHmm').diff(moment('1242', 'HHmm'));

Would do something like that, I didn’t try it so you maybe need to correct it.

EDIT :

    let diff = moment('12:42', 'HH:mm').diff(moment('10:27', 'HH:mm'))
    let d = moment.duration(diff);
    return Math.floor(d.asHours()) + moment.utc(diff).format(":mm");

I think my solution is not the best, maybe you should try other things ahah

based on my time two difference time result should be shown 1:05
but get 1:00
below my code

let diff = moment(parseInt(this.endTime), 'H:m').diff(moment(parseInt(this.startTime), 'H:m'))
    let d = moment.duration(diff);
    let totaltime =Math.floor(d.asHours()) + moment.utc(diff).format(":mm");
    alert(totaltime)

how can i fix that.

Can you console.log(parseInt(this.endTime)) and console.log(parseInt(this.startTime)) please ? Just take my code upper in the topic, it is working, ive tried it

8

its showing NaN


private startTime:number;
private endTime:number;
let diff = moment(this.endTime, 'H:m').diff(moment(this.startTime, 'H:m'))

    let d = moment.duration(diff);
    let totaltime =Math.floor(d.asHours()) + moment.utc(diff).format(":mm");
    alert(totaltime)

where i’m wrong?

Why are you passing number when it’s waiting for string ? Show your variables startTime and endTime

its working properly right now

11

can i change the formal 1:01 to 1 hour 01 minute?

12

Math.floor(d.asHours()) +" hours " + moment.utc(diff).format("mm") + " minutes";

Something like that I suppose

now actually i want to calculate amount based on time

supercharges $40;

hourlyCharge : number =40;
this.totalammout=   this.hourlyCharge * parseInt(this.total);
    console.log("Total ammount"+this.totalammout)
    let diff = moment(this.endTime, 'H:m').diff(moment(this.startTime, 'H:m'))
    let d = moment.duration(diff);
    this.total =Math.floor(d.asHours()) +" hours " + moment.utc(diff).format("mm") + " minutes";
    //alert(this.total)

I try to do look like this for calculating the amount based on time
How can i do that.

I feel like Im doing your job because you are too lazy to do it yourself. Based on the fact that you are a member for at least one year on this forum, you are more than capable to achieve this alone, so it will be the last time I help you:

let diff = moment(this.endTime, 'HH:mm').diff(moment(this.startTime, 'HH:mm'))
let d = moment.duration(diff);
let hours =  Math.floor(d.asHours());
let minutes = moment.utc(diff).format("mm");
this.totalAmount = hours * hourlyCharge + parseInt(minutes) * hourlyCharge/60;
this.total =hours +" hours " + minutes + " minutes";
