day incorrect in angular material datepicker

Question

When I select a date I see the correct date in the field but, when I save, the datepicker send the day before the date I have selected ( 3 hours offset ) i am using angular

Answer 1

If the hour of the date is equal to 0, it means we are in the same timezone and you don't need to do something.

If the hour of the date is greater than 12, it means the date is the day of yesterday and you need to add a day.

If the hour of the date is lower than 12, it means the date is the day tomorrow and you need to correct it.

Below, a small function that may helps you as it helps me

let date = new Date(dateReceived);
//We use dayCorrector to remove the timezone. We want brut date without any timezone
let dayCorrector = (date.getHours()>12) ? (1) : (date.getHours()<=12) ? (-1) : (0);
date.setDate(date.getDate()+dayCorrector);
let dateFinal = (String(date.getFullYear()) +'-'+ String(date.getMonth()+1) +'-'+ String(date.getDate())+' 00:00:00Z');
