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. Given 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.

The 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. The 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. It is necessary to memorize these dates to be able to determine the day of the week, given any date. February's doomsday occurs on the last day of the month, or the 28 th in a typical year or the 29 th in a leap year. March's doomsday can be remembered as the first 3 digits of π, 3. The remaining odd months can be remembered using the mnemonic "I work from 9 to 5 at The 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 was Tuesday. For it was Wednesday, and for it will be a Sunday. Just Married. Work From Home.

Within this calendar, a standard year consists of days with a leap day being introduced to the month of February during a leap year. The months of April, June, September, and November have 30 days, while the rest have 31 days except for February, which has 28 days in a standard year, and 29 in a leap year.

The Gregorian calendar is a reformed version of the Julian calendar, which was itself a modification of the ancient Roman calendar. The ancient Roman calendar was believed to be an observational lunar calendar, based on the cycles of the moon's phases. The Romans were then believed to have adopted a month calendar with days, leaving the remaining 50 or so days as an unorganized winter.

This calendar allowed the summer and winter months to become completely misplaced, leading to the adoption of more accurate calendars. The Republican calendar later used by Rome followed Greek calendars in its assumptions of From this point, many attempts were made to align the Republican calendar with the solar year including the addition of an extra month to certain years to supplant the lack of days in a particular year.

In 46 BC, the calendar was further reformed by Julius Caesar, introducing an algorithm that removed the dependence of calendars from the observation of the new moon. In order to accomplish this, Caesar inserted an additional 10 days into the Republican calendar, making the total number of days in a year He also added the intercalation of a leap day every fourth year, all in an attempt to further synchronize the Roman calendar with the solar year.

Despite all efforts, the Julian calendar still required further reform, since the calendar drifted with respect to the equinoxes and solstices by approximately 11 minutes per year. By , this resulted in a difference of 10 days from what was expected. Pope Gregory XIII addressed this by essentially skipping 10 days in the date, making the day after October 4, , October An adjustment was also made to the algorithm of the Julian calendar that changed which century years would be considered leap years.

Under the Gregorian calendar, century years not divisible by would not be leap years. These changes reduced the error from 1 day in years, to 1 day in 3, years with respect to the current value of the mean solar year. The adoption of the Gregorian calendar occurred slowly over a period of centuries, and despite many proposals to further reform the calendar, the Gregorian Calendar still prevails as the most commonly used dating system worldwide.
