60 Day Calculator
Enter a start date and the number of days to add or subtract. Choose calendar days or business days only (weekdays, no weekends). The result shows the exact end date, the weekday it falls on, a countdown from today, and time-unit conversions including hours, minutes, weeks, and seconds. The default is 60 calendar days from today.
What is the 60 Day Calculator?
The 60 Day Calculator is a date arithmetic tool that finds the exact date 60 days (or any number of days) from any starting date, in either direction. Enter a start date and a day count, then choose whether to go forward or backward and whether to count every calendar day or only business days (weekdays, skipping Saturday and Sunday). The result shows the destination date along with its weekday name, a countdown from today, and time-unit conversions so you can see the span in hours, weeks, and seconds. Common uses include calculating contractor payment deadlines, insurance grace periods, probation end dates, warranty claims, and challenge timelines like a 60-day fitness program.
Calendar days vs. business days
A calendar day is simply any day on the calendar, including weekends and public holidays. A business day is typically defined as Monday through Friday, excluding weekends. This calculator skips Saturday and Sunday when business-day mode is active, but it does not remove public holidays because these vary by country, region, and industry. If your contract or legal agreement specifies that holidays must also be excluded, subtract the number of holidays that fall in the period from the result. For most practical purposes, 60 business days equals roughly 84-86 calendar days, depending on how many Saturdays and Sundays fall in the window.
How the date calculation works
For calendar days, the formula is simple: take the start date and add or subtract the specified number of days. February is handled correctly, including in leap years, so adding 28 days to February 1 gives March 1 in a common year and March 1 in a leap year (since 28 days from Feb 1 still lands in February in a leap year, while 29 days would give Mar 1). For business days, the calculator steps forward (or backward) one day at a time and skips any day whose weekday falls on Saturday (day 6) or Sunday (day 0) until the required count is reached. Both modes account for month-boundary rollovers and year transitions automatically.
Practical uses of a 60-day window
Sixty days appears in dozens of everyday legal and financial contexts. Under U.S. federal regulations, many agencies use a 60-day comment or response period. The Fair Credit Billing Act gives cardholders 60 days to dispute a charge. Many landlords require 60 days notice before a lease ends. Suppliers and contractors frequently quote Net-60 payment terms, meaning invoices are due 60 calendar days after the invoice date. In health and fitness, 60-day challenges are popular because two months is long enough to build a habit but short enough to maintain motivation. Knowing the precise end date at the outset makes it easier to plan, track, and enforce these windows.

Frequently asked questions
What date is 60 days from today?
The result depends on today's date, which the calculator reads automatically. To find the date 60 days from today, leave the start date as today and enter 60 in the day count field with the direction set to "Add." The calculator will display the exact calendar date along with the day of the week it falls on.
What is 60 business days from today?
Sixty business days from today is roughly 84-86 calendar days later, depending on the number of weekend days in the span. Switch the "Day type" selector to "Business days (Mon-Fri only)" to get the precise date. The calculator skips every Saturday and Sunday while counting up to 60 weekdays.
How do I calculate 60 days before a date?
Set the "Direction" selector to "Subtract (backward in time)," enter the target date as your start date, and type 60 in the day count field. The result will be the date 60 calendar days before that date. You can also use this to find a notice deadline, e.g. if your lease ends on a specific date and you need to give 60 days notice, the result tells you the latest day to submit that notice.
Does the calculator account for leap years?
Yes. Date arithmetic handles February 28 and February 29 correctly. If your 60-day window crosses the end of February in a leap year, the extra day is included automatically. Adding 30 days to January 31 gives March 2 in a common year and March 1 in a leap year.
Are public holidays excluded from the business-day count?
No. The business-day mode skips Saturdays and Sundays only. Public holidays such as Christmas, New Year, or bank holidays vary by country, region, and employer, so they cannot be removed universally. If your agreement explicitly excludes specific holidays, count how many fall in the window and add that number to the day count to compensate.
How many hours are in 60 days?
Sixty calendar days contain 60 x 24 = 1,440 hours, 86,400 minutes, and 5,184,000 seconds. The calculator shows all these conversions automatically in the output panel.
How many weeks is 60 days?
Sixty days divided by 7 gives approximately 8.57 weeks, meaning 8 complete weeks plus 4 extra days. If you need whole weeks, that is 8 full weeks with a 4-day remainder.
