# Days from today: what date is it? Finds the date a number of calendar days or working days after or before today or any start date, skipping weekends and public holidays when asked. - Page: https://www.acalculator.org/days/fromtoday-calculator - JSON spec: https://www.acalculator.org/days/fromtoday-calculator.json - Version: 5014b0777295 ## Default answer Example with the default inputs (Number of days 90, Start date October 5, 2026, Count working days only No) on the example date Monday, October 5, 2026: 90 calendar days after October 5, 2026 is Sunday, January 3, 2027. ## Inputs | Key | Label | Description | | --- | --- | --- | | days | Number of days | How many days to count. A negative number counts back into the past. | | start | Start date | The date to count from. Today, unless you change it. | | useWorkingDays | Count working days only | Count only working days instead of every calendar day. | | excludeSaturday | Skip Saturdays | Leave Saturdays out of the count. | | excludeSunday | Skip Sundays | Leave Sundays out of the count. | | excludeHolidays | Skip public holidays | Leave the chosen country's public holidays out of the count. | | country | Country | The country whose public holidays are skipped. | ## Outputs | Key | Label | Description | | --- | --- | --- | | date | Date | The date the given number of days after the start date, or before it for a negative number. | | what | Counted | How many calendar or working days were counted, and which way: for example “1 working day before” or “90 calendar days after”. | | weekday | Day of the week | The weekday of the result date. | | dayOfYear | Day of the year | The result date’s day number in its year, 1 to 366. | | week | ISO week | The ISO 8601 week number of the result date (weeks start on Monday; week 1 holds the first Thursday). | | calendarDays | Calendar days | Calendar days from the start date to the result date. Negative when the result is earlier. | | skipped | Days skipped | Weekend days and public holidays passed over while counting working days. | ## Method Add the number of days to the start date; for working days, step one day at a time and count only days that are not a chosen weekend day or an observed public holiday. ## Assumptions - The start date itself is not counted: 1 day from Monday is Tuesday, and 1 working day from Friday is the next Monday. - A negative number counts back in the same way: −1 working day from Monday is the Friday before. - Dates are calendar days with no time of day, so daylight-saving changes cannot add or lose a day. - Public holidays are the days off as observed (a holiday on a weekend moves to a weekday where the country’s rule says so). Holiday data covers the US from 1986, the UK (England and Wales) from 2019 to 2028, Canada (federal) from 2021, India (central government) from 2023 to 2027, and China from 2015 to 2035. - Week numbers follow ISO 8601: weeks start on Monday, and week 1 is the week with the year’s first Thursday. ## Worked examples 1. days = 90, start = 2026-09-27, useWorkingDays = no gives what = 90 calendar days after, date = 2026-12-26, weekday = Saturday, dayOfYear = 360, week = 52, calendarDays = 90. 2. days = 1, start = 2026-09-25, useWorkingDays = yes, excludeSaturday = yes, excludeSunday = yes, excludeHolidays = no gives what = 1 working day after, date = 2026-09-28, weekday = Monday, calendarDays = 3, skipped = 2. 3. days = 10, start = 2026-12-20, useWorkingDays = yes, excludeSaturday = yes, excludeSunday = yes, excludeHolidays = yes, country = us gives what = 10 working days after, date = 2027-01-05, calendarDays = 16, skipped = 6, week = 1.

To calculate days from today, simply add or subtract the number of days from the current date. For example, 30 days from today would be today's date plus 30 days. Our calculator automatically handles month and year transitions, including leap years. ### What's the difference between calendar days and business days? Calendar days include all days (weekends and holidays), while business days exclude weekends and holidays. Business days are typically Monday through Friday. For example, 5 business days from Monday would be the following Monday, while 5 calendar days would be Saturday. ### How do I calculate working days from today? Working days exclude weekends (Saturday and Sunday) and holidays. To calculate working days, count only Monday through Friday, excluding any holidays. Our calculator can automatically exclude weekends and public holidays when you turn on “Count working days only”. The start date itself is not counted, so 1 working day from a Friday is the next Monday. ### What if I need to calculate days in the past? You can calculate days in the past by entering a negative number. For example, -7 days from today would be 7 days ago. This is useful for finding dates in the past or calculating how many days have passed since a specific event. ### How does the calculator handle leap years? Our calculator automatically accounts for leap years. In leap years, February has 29 days instead of 28, which affects calculations spanning February 29th. The calculator uses the standard Gregorian calendar rules for leap year determination. ### Can I calculate specific time periods like weeks or months? Yes. You can calculate weeks by multiplying by 7 (e.g., 2 weeks = 14 days). The calculator counts days, not months, so for a month enter the number of days in it (28 to 31), or use about 30 days as an estimate. ### What are common uses for this calculator? This calculator is useful for planning events, calculating deadlines, determining payment due dates, planning travel, tracking project timelines, calculating return periods, and any situation where you need to know a future or past date. ### How accurate is the calculation? Our calculator accounts for leap years, varying month lengths, and calendar rules. It counts whole calendar days with no time of day, so daylight-saving changes cannot add or lose a day. ### Can I calculate dates across year boundaries? Yes! The calculator handles year transitions automatically. For example, if today is December 30th and you calculate 5 days from today, it will correctly show January 4th of the next year. This works for both future and past calculations. ### How do I use this for project planning? For project planning, calculate working days to estimate realistic timelines. For example, if a task takes 10 working days, you can calculate when it will be completed. This helps create accurate project schedules that account for weekends and holidays. ## Sources - U.S. Office of Personnel Management, Federal Holidays (5 U.S.C. 6103 and the weekend rule). https://www.opm.gov/policy-data-oversight/pay-leave/federal-holidays/ - GOV.UK, UK bank holidays (England and Wales). https://www.gov.uk/bank-holidays - Canada Labour Code, section 166, general holidays. https://laws-lois.justice.gc.ca/eng/acts/L-2/ - ISO 8601-1:2019, Date and time, week numbering (week 1 holds the first Thursday of the year).
