TOOLHow long until your date?
Pick any date and this tool tells you exactly how many days, weeks and months away it is — and which day of the week it falls on. Choose a past date and it flips to show how many days have gone by since. It all runs in your browser.
How it's counted
Days are counted as whole calendar days from today to your target. Tomorrow is 1 day away; a date last week shows the days since. Months are an approximate figure (days ÷ 30.44) since months vary in length.

A worked example
If today is 1 June and your target is Christmas Day, entering 25 December returns 207 days. The tool counts whole calendar days from today to your date, including weekends, and updates the moment you pick a new date — so you always see the current number without doing any mental arithmetic across months.
What people count down to
Common targets include holidays like Christmas or New Year, a birthday or anniversary, a vacation, a wedding, an exam or project deadline, a due date, or a retirement. Knowing the exact number of days helps you plan backwards — booking, saving or preparing on a realistic schedule.
Want a live ticking display down to the second? Use the countdown timer. To count only working days, use the business days calculator, and to measure a gap between two past or future dates, read days between dates.
Frequently asked questions
How do I calculate days until a date?
Subtract today's date from the target date and count the whole days in between. This tool does it instantly and also shows the total in weeks and months.
Does it count today?
It counts full days from today to the target date. A date tomorrow shows 1 day; today shows 0 days.
Can I use a past date?
Yes. Pick a past date and the tool shows how many days have passed since then instead.
