Please provide a proper way to call this method from LWC passing date parameter.

public with sharing class ApexClass {
    @AuraEnabled(cacheable = true) 
    public Date string apexMethod(Date z) {
        return z;

We got date type in aura component for this situation. Any such way in LWC?

Hi i have used following code -

APEX Class -

    public static Date getDate(Date dt)
        System.Debug('dt '+dt);
        return dt;


and JS Code -

  { if(data){


 @wire(getDate,{dt:new Date("2019-12-31")})
   { if(data){


And for My understanding, the date parameter accepts in YYYY-MM-DD format.

    I feel really great to know Date is accepting 'YYYY-MM-DD' format. Thank you so much Commented Jan 23, 2020 at 12:56
  • Could you give DateTime format as well? Commented Jan 23, 2020 at 13:04

The first thing is your apex method return value is wrong. Your method expect a string value to return but you are returning a date value.

The correct code is:-

@AuraEnabled(cacheable = true) 
public static string apexMethod(Date z) {
    return String.valueOf(z);

Now, to call it from LWC, You can pass a date object value as parameter from JavaScript code:-

import { LightningElement } from 'lwc';
import apexMethod from '@salesforce/apex/ContactController.apexMethod';

export default class CurrencyInputField extends LightningElement {
     handleChange() {
        var d = new Date();
        apexMethod({ z: d })
            .then(result => {
                JSON.stringify('result ' + result);
            .catch(error => {
                JSON.stringify('error ' + error);
