Some useful information regarding to the date duration calculator:
- The number of days between two dates can be calculated, for example, “15 November 1974” is ten days after “5 November 1974” in the Gregorian calendar. A particular day may be represented by a different date in another calendar as in the Gregorian calendar and the Julian calendar, which have been used simultaneously in different places.
- In most calendar systems, the date consists of three parts: the day of the month, the month, and the year. There may also be additional parts, such as the day of the week. Years are usually counted from a particular starting point, usually called the epoch, with era referring to the particular period of time (note the different use of the terms in geology).
- The most widely used epoch is a conventional birthdate of Jesus.
