within this calendar, a standard year consists of 365 days with a leap day being introduced to the month of february during a leap year. the ancient roman calendar was believed to be an observational lunar calendar, based on the cycles of the moon’s phases. 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. pope gregory xiii addressed this by essentially skipping 10 days in the date, making the day after october 4, 1582, october 15. an adjustment was also made to the algorithm of the julian calendar that changed which century years would be considered leap years.
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. although certain holidays, such as christmas and new year’s day, are widely celebrated worldwide, most countries have their own set of holidays that are specific to the country, and even the same holidays may be observed differently within countries: some may receive a full suspension of typical daily activities, while others may only get partial days off. for a further level of specificity, federal holidays in the u.s. refer to holidays that have been recognized by the u.s. government; on these days, non-essential federal government offices are closed, and all federal employees receive paid leave. in some cases, an employee who is required to work on a federal holiday may receive compensation in the form of holiday pay in addition to their regular wages. another widely observed holiday in the u.s., thanksgiving, occurs on a “floating thursday,” the fourth thursday in november, hence the dates of these holidays vary by year.

the 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. to use the day counter, use the drop-down menus to select a starting month, date, and year. alternatively, selecting april 25th as the end day and not checking the “include end day” box would provide the same result. 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. 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. given a start date and a selected number of days to add or subtract, the calculator will determine the resulting date. the calculator also shows the day of the week for the chosen dates.
the algorithm is based on “doomsdays,” which are specific dates that all fall on a certain day of the week in a given year. it is necessary to memorize these dates to be able to determine the day of the week, given any date. march’s doomsday can be remembered as the first 3 digits of π, 3.14 (3/14). 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. 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: thus, the anchor day in the year 1500 (1900 – 400) is also a wednesday.
