This free online calculator will calculate the number business days between two dates, or calculate an ending date based on a specified number of business days to add or subtract to or from a starting date. Show Plus, unlike other working days calculators, this calculator will not only let you choose which days of the week you want to be counted as business days, but it also allows you to indicate which, if any, holidays you would like excluded from the count. This customization feature means you can also use the calculator to count work days only (working days calculator), or any other types of events that are counted based on which days of the week they reoccur. If you would like to calculate the years, days, weeks, hours, and minutes between two dates, please visit the Date Difference Calculator. Many Fun Uses!Here are just a few of the many uses for this business days calculator:
Frequently searched business days from today (), excluding weekends and federal holidays (*): See chart on this page for other common searches, or use the Business Days Calculator below for custom workdays and holidays. Use this counter to find the number of days between two dates, including the number of working days, weekends, and holidays. Click "Settings" to define holidays. Count Days from a DateThe day counter or days calculator above can be used in situations such as counting down to a birthday, counting the number of days into a pregnancy, the number of business days left for a project, etc. How to use the day counterTo use the day counter, use the drop-down menus to select a starting month, date, and year. Check the "include end day" box if the end day should be included in the count. For example, if a project is due at 11:59 PM on April 24th, and the current day is March 29th, select those dates, and use the check box to include the end day. Alternatively, selecting April 25th as the end day and not checking the "include end day" box would provide the same result. The calculator has additional settings, accessible by clicking the "Settings" link. Select whether or not to include holidays. If you would like to include holidays, select which common US holidays to include, and/or use the table below to enter other holidays. The calculator result will include a count of the number of holidays included in the chosen time span. The calculator returns the number of days between the selected date assuming a Monday to Friday work week and that the weekend falls on Saturday and Sunday. It breaks down the total number of days into weekend days and weekdays by default, but can also include common or specified holidays (both in the count as well as listing the holidays). The calculator always counts the start date as a full day, and counts the last date as a full day if the "include end day" box is selected. If the box is not selected, the end date is not included in the calculation. Counting days from a dateGiven a start date and a selected number of days to add or subtract, the calculator will determine the resulting date. The "count business days only" checkbox determines whether or not the selected number of days includes weekends. For example, if the box is checked, the day selected is a Monday, and if 7 days were added to that, the calculator result will be Wednesday the following week, not Monday, since Saturday and Sunday would not be counted. Day of the weekThe calculator also shows the day of the week for the chosen dates. There are many different algorithms for calculating the day of the week. One of these is referred to as the Doomsday rule, an algorithm developed by John Conway that, with practice, can be done mentally. DoomsdaysThe algorithm is based on "doomsdays," which are specific dates that all fall on a certain day of the week in a given year. These dates are the same for every year, but the day they all fall on changes with each year. The table below shows the doomsdays for each month of the year. Doomsdays by month
*On a leap year, the doomsday for January is 1/4 instead of 1/3 and the doomsday for February is 2/29 instead of 2/28. It is necessary to memorize these dates to be able to determine the day of the week, given any date. For the even months, except for February, all of the doomsdays occur on the day corresponding to the given month (4/4, 6/6, 8/8, 10/10, 12/12). February's doomsday occurs on the last day of the month, or the 28th in a typical year or the 29th in a leap year. January's occurs on the 3rd, or 4th during a leap year (1/3 or 1/4). March's doomsday can be remembered as the first 3 digits of π, 3.14 (3/14). The remaining odd months can be remembered using the mnemonic "I work from 9 to 5 at 7-11." July can be remembered along with November, where July's doomsday falls on 7/11 and November's is the same except that the day and month are switched (11/7). Similarly, September can be remembered as "working 9 to 5," or 9/5, where May's doomsday is the same, again with the position of the day and month switched (5/9). Anchor dayThe anchor day is the doomsday for a given century. The doomsday for a given year is calculated relative to the anchor day for the century. For example, the doomsday for the year 2000 was Tuesday. For 1900 it was Wednesday, and for 2100 it will be a Sunday. The Gregorian calendar (the most widely used calendar) cycles every 400 years. Thus, it is only necessary to memorize the anchor day for four centuries. Any other anchor day for any century can be determined relative to the anchor days for any chosen consecutive span of four centuries. For example, using the centuries 1900, 2000, 2100, and 2200, their anchor days are as follows: Anchor days by century
Thus, the anchor day in the year 1500 (1900 - 400) is also a Wednesday. In the year 3000 (2200 + 400 + 400), the anchor day will be a Friday, and so on. To perform the algorithm, it is also necessary to assign numbers to each day of the week: Numerical representation of days of the week
Given that the above is memorized (or can be referenced), determining the day of the week given any date just requires the use of basic arithmetic and the following set of rules. The Doomsday ruleThe algorithm is as follows:
Example: What day was 3/15/2292?
Thus, 3/15/2292 was a Tuesday. How many days is 2022 minus weekends?260 Days: That's the total number of working days in the year 2022.
How many days are in a month without weekends?It typically ranges between 19-22 days, considering a 5-day workweek. Since the number of days varies from month to month, the number of workdays also varies.
How long is a 5 business day?Five business days is five days plus any days that are deemed non-business days, such as weekends or holidays. For example, five business days from a Wednesday is actually seven days total because you have to add Saturday and Sunday (non-business days) to the number of business days.
How many days is 3 Businessdays?3 business days is 3 working days, not counting weekends or public holidays. Generally speaking, business days are Monday through Friday and do not include weekends. This means that if something will take up to 3 business days to process, it does not necessarily mean only 3 days.
