count how many days till christmas in javascript

You can use JavaScript's built-in Date object to determine the current date and time, and calculate the number of days between it and Christmas. Here is an example code snippet:


index.tsx
// Set the date for Christmas
const christmasDate = new Date('December 25, 2021 00:00:00');

// Get the current date
const today = new Date();

// Calculate the time difference between today and Christmas
const timeDiff = christmasDate.getTime() - today.getTime();

// Calculate the number of days between today and Christmas
const daysTillChristmas = Math.ceil(timeDiff / (1000 * 3600 * 24));

console.log(`There are ${daysTillChristmas} days till Christmas!`);
463 chars
14 lines

This code first creates a Date object for Christmas and another one for today. It then calculates the time difference between those dates in milliseconds and converts it to days. Finally, it logs the number of days until Christmas to the console.
