Date Calculator — day of the week, week number and days left

Date Info answers the small calendar questions in one place: today’s date in mm/dd/yyyy, the day of the week, the week number, and a date calculator that counts the days between any two dates or adds days to one.

How to use Date Info

The top of the page always shows the current date, written out fully — month, day and year — together with the weekday and the week number of the year. That alone settles two questions people ask constantly: what is the date today in mm/dd/yyyy, and what is today’s date and day of the week. Both are read from your device, so they are correct wherever you are.

Below the header sit the tools. Pick the one that matches your question: Days between two dates — for “how long ago” and “how long until”. Add or subtract days — for deadlines like “45 days from today”.

Weekday lookup — what day of the week any past or future date falls on. Countdown — a running timer to a date you choose.

A date calculator for questions people actually ask

Most date arithmetic goes wrong at the edges: months have different lengths, February misbehaves in leap years, and it is easy to be off by one depending on whether you count the first day. The calculator handles all of that for you — give it two dates and it returns the exact number of days, weeks and months between them. It works both ways: forward for deadlines and countdowns, backward for “what date was 90 days ago”. It is a free date calculator in the plainest sense — no account, no download, no limit on how often you use it.

The yyyy part matters more than it looks. Writing years in full avoids the classic two-digit ambiguity, and the tools here accept and display four-digit years everywhere, so a date is never a guess.

Time now: USA, Los Angeles and UTC

Dates travel badly across time zones — it can be Tuesday in one place and still Monday in another. That is why the page also shows the time: if you need the USA date and time now, remember that the country spans several zones, so the date can differ from coast to coast around midnight. The date and time in Los Angeles follow Pacific Time; the date and time now in UTC are the neutral reference the internet runs on. When you file, book or publish something across borders, check which of those three clocks the deadline actually lives in.

Half of all date arguments are really an argument about whether to count the first day. Decide that before you count, not after.

Sunrise, sunset and countdowns

A date is more than a number: the day has a shape. Enter a date and a place and you can check sunrise and sunset times by date — useful for photographers, runners, drivers and anyone planning around daylight. And if the date you care about is still ahead, put a countdown timer on that date and let the page keep score: it shows the remaining days shrinking as the day approaches, which beats re-counting every morning.

Questions and answers

What is the date today in mm/dd/yyyy?
It is shown live at the top of this page, in the month/day/year order used in the United States — two digits for month and day, four for the year.
What is today’s date and day of the week?
Both appear together in the header — the full date and the weekday name next to it, along with the current week number of the year.
Is there an online date calculator here that subtracts dates?
Yes. Enter a start date and an end date and it returns the difference in days; swap the direction and it subtracts a number of days from any date instead.
