# Date Countdown Calculator

Select an event date to see the remaining or elapsed calendar time.

## Input data

- **Target date** - type: date; default: 2027-01-01

## How it works

Countdown = target date − today, using local calendar dates at midnight.

## Quick examples

- **New Year 2027** - Target date: 2027-01-01
- **Summer 2027** - Target date: 2027-06-21
- **Past date** - Target date: 2020-01-01

## Understanding your result

A positive result is still ahead, zero is today, and a negative interval means the date has passed.
