Day estimator: the date N days from today
A lot of date questions are really “what date will it be in X days?”: a parcel that arrives in 5–7 business days, an invoice due in 30 days, a 90-day return window or a 100-day fitness challenge. Open Add or subtract, tap a quick pick from +7 to +365 days, and the estimator shows the date, its weekday and its ISO week.
Shortcuts: 30 days from today · 60 days · 90 days · 100 days · 180 days · 1 year · 10 business days
| Ordered on | Arrives by |
|---|---|
| Monday | Monday of the next week |
| Wednesday | Wednesday of the next week |
| Friday | Friday of the next week |
| Saturday or Sunday | Friday of the next week (counting starts Monday) |
Public holidays are not skipped automatically. Around Thanksgiving, Christmas or a bank holiday, add a day for each holiday that falls inside the range.
Days between two dates
Pick a start and an end date to get the difference in days, plus the same span in weeks and in years, months and days. Tick business days only to leave out Saturdays and Sundays, and include end date when both the first and the last day count, for example for a hotel stay or a leave request.
Adding days: 30, 60 and 90-day deadlines
Return windows, trial periods, payment terms (“net 30”) and probation periods are usually written in days. Start from the date in the document and add the number of days to get the deadline.
| Add | Result | Weekday |
|---|---|---|
| 14 days | Nov 18, 2026 | Wednesday |
| 30 days | Dec 4, 2026 | Friday |
| 60 days | Jan 3, 2027 | Sunday |
| 90 days | Feb 2, 2027 | Tuesday |
| 180 days | May 3, 2027 | Monday |
Adding months is not the same as adding days
One month after January 31 has no exact answer, because February has no 31st. The calculator moves to the last day of the shorter month (February 28, or 29 in a leap year). That is why “3 months” and “90 days” from the same date can end on different days.
For ages, use the age calculator. For a live count to a date, use the countdown.
Frequently asked questions
Does the calculator count the start date?
By default it counts the days between the dates, like subtracting one from the other. Tick “include end date” to count both the first and the last day.
Are public holidays excluded from business days?
No. Business days leave out Saturdays and Sundays only, because holidays differ by country and state. Subtract them yourself if you need to.
How many days are there between two dates in different years?
Enter both dates. Leap years, including February 29, 2028, are handled automatically.
What date is 90 days from today?
Open the 90-day estimate: it shows the exact date and weekday, counted from your device’s today.
What is a day estimator?
A tool that answers “what date is it N days from now?”. Here it is built into the date calculator: pick a number of days, or business days, and get the resulting date.
