★ TIME & DATE · DAYS FROM TODAY · DATE MATH
120 days from Wednesday, October 28, 2026 is Thursday, February 25, 2027 — with 86 weekdays and 80 business days in between. Add any number of days to any date and see the result date, the weekday, and how many weekdays and business days the span holds — or go back with days-ago, or count the days between two dates. This one is the 120-DAYS-FROM-TODAY tool — a start date plus a number of days, with the weekday and the business-day count — the 45-days-from-today-calculator page is the 45-DAYS tool — the same calculation for 45 days — not 120; the 30-days-from-today-calculator page is the 30-DAYS tool — the same calculation for 30 days — not 120; the date-calculator page is the DATE tool — add or subtract days from any date — the plain version, without the weekday and business-day count; and the days-between-dates-calculator page is the DAYS-BETWEEN tool — the gap between two dates — not adding days to one date.
Add 120 days to today — or any number of days to any date — and see the result date, the weekday, and how many weekdays and business days the span holds. On the defaults it is Wednesday, October 28, 2026 plus 120 days: Thursday, February 25, 2027, with 86 weekdays and 80 business days in between.
It means that 120 days after Wednesday, October 28, 2026, the calendar reads Thursday, February 25, 2027. 3 of the 120 days are used up finishing October, 30 land in November, 31 land in December, 31 land in January and 25 in February. The weekday follows from the count: 120 days is 17 weeks plus 1 days, so the weekday moves 1 days forward from Wednesday to Thursday. The span holds 86 weekdays — Monday to Friday, October 29 through February 25 — and 80 business days, because 6 of those weekdays are US federal holidays: Veterans Day, November 11, 2026, Thanksgiving, November 26, 2026, Christmas, December 25, 2026, New Year's Day, January 1, 2027, Martin Luther King Jr. Day, January 18, 2027 and Presidents Day, February 15, 2027.
The start date does not count. Adding 120 days to October 28 lands on Thursday, February 25, 2027, not the day after: the count starts on October 29, the day after the start. If you count the start date as day one, every answer comes out one day late. The weekdays and business days are counted the same way — the days after the start date through the result date, inclusive.
Weekdays and business days are different numbers. The 120-day span holds 86 weekdays but only 80 business days, because 6 federal holidays fall inside it. A span in January would lose Martin Luther King Jr. Day; a span in July would lose Independence Day. The calculator counts US federal holidays on their calendar dates — a holiday that falls on a Saturday or Sunday costs no business day, because it was never a weekday.
Months and leap years are handled by the calendar, not by arithmetic. Adding 120 days is not adding three months: 120 days from October 28 is Thursday, February 25, 2027, but 120 days from November 28 is Sunday, March 28, 2027, and 30 days from February 28, 2028 is Wednesday, March 29, 2028 — because 2028 is a leap year and February has 29 days. The calculator adds days to the real calendar, so month lengths and leap days are never guessed.
On the defaults: start Wednesday, October 28, 2026, add 120 days.
And the other way: 120 days before October 28, 2026 is Tuesday, June 30, 2026, and the smallest number of days to add to reach Friday, January 1, 2027 is 65 — at 64 days you land on Thursday, December 31, 2026.
The defaults are a start date of October 28, 2026 — today — and 120 days to add, chosen because "120 days from today" is the question people actually type. They are a starting point, not a lesson: change the start date to any date, change the days to 30, 45, 60 or 90, switch to days-ago to go backwards, or switch to days-between to count the gap between two dates. Business days are US federal holidays on their calendar dates — New Year's Day, Martin Luther King Jr. Day, Presidents Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving and Christmas — with no observed-shift for holidays that fall on a weekend, and no state or local holidays. A date that does not exist, like February 30, is refused instead of rolling over to March.
These notes repeat in every explainer section because this page is built to be read start to finish: the start date does not count; weekdays and business days are different numbers; and months and leap years are handled by the calendar, not by arithmetic.

Dates are exact calendar arithmetic: the result date, the weekday, the weekday count and the business-day count are all computed from the real calendar, including month lengths and leap years — February 29, 2028 exists, and the calculator lands on it. Business days are weekdays minus US federal holidays on their calendar dates, with no observed-shift for holidays that fall on a weekend and no state, local or company holidays — a span that crosses a state holiday will show one business day too many. The calculator counts the days after the start date through the result date, inclusive, and the start date itself never counts. It works for any date the calendar covers; dates before the Gregorian calendar are out of scope.

120 days from Wednesday, October 28, 2026 is Thursday, February 25, 2027. 3 of the 120 days are used up finishing October, 30 land in November, 31 land in December, 31 land in January and 25 in February.
The 120 days from October 28, 2026 hold 86 weekdays. That is every Monday to Friday from October 29 through February 25.
80 business days — the 86 weekdays minus Veterans Day, November 11, 2026, Thanksgiving, November 26, 2026, Christmas, December 25, 2026, New Year's Day, January 1, 2027, Martin Luther King Jr. Day, January 18, 2027 and Presidents Day, February 15, 2027, the federal holidays in the span.
120 days before Wednesday, October 28, 2026 was Tuesday, June 30, 2026. The span back holds 86 weekdays and 84 business days.
Subtract the earlier date from the later one — from October 28 to Thursday, February 25, 2027 is 120 days. The start date does not count; the days after it through the end date do.
A federal holiday that falls on a weekday is not a business day, but it is still a weekday. Veterans Day, November 11, 2026 is one of the 86 weekdays in the 120-day span and not one of the 80 business days.
Yes — February 28, 2028 plus 1 day is Tuesday, February 29, 2028, because 2028 is a leap year. The calculator adds days to the real calendar, so month lengths and leap days are never guessed.
30 days from Wednesday, October 28, 2026 is Friday, November 27, 2026. The span holds 22 weekdays and 20 business days.
