JavaScript Date and Time

Creating Dates

const now = new Date();
const specific = new Date(2025, 11, 19);
const fromString = new Date('2025-12-19');

Getting Date Parts

const date = new Date();

date.getFullYear();  // 2025
date.getMonth();     // 11 (0-11)
date.getDate();      // 19
date.getDay();       // 5 (0-6, Sunday=0)

Formatting Dates

const date = new Date();
date.toLocaleDateString(); // "12/19/2025"
date.toISOString();        // "2025-12-19T..."

Key Takeaway

Date object handles dates and times. Get parts with get methods. Format with toString methods. Essential for any app with dates.
