How many days until Christmas? Until New Year, Halloween, Valentine's Day — or just until Friday? This calculator answers instantly: pick a holiday or any calendar date and see the number of days left, computed live from your device's clock the moment the page opens.
Holidays resolve themselves: choose Christmas and the tool automatically counts to the next December 25, whether that is this year or the following one — the same for New Year, Halloween and Valentine's Day, while the Friday option finds the next end of the workweek. Alongside the day count you get a weeks-and-days breakdown and the full weekday date of the target, and if the chosen day is today, the calculator celebrates with an "it's today!" message instead of a zero.
Everything runs locally in your browser: no server calls, no stored dates, no stale pre-computed numbers — reload the page tomorrow and the countdown will simply be one day shorter. Any calendar date works as a target, from a birthday to a visa deadline.
Need different date math? The date difference calculator measures the exact span between any two dates in years, months and days, and the countdown timer ticks down to a precise moment in hours, minutes and seconds.
