If you are working with NAV / Dynamics 365 Business Central, you will hear the term Date Formula. A date formula is a formula, abbreviated using combination of signs, letters and numbers, to calculate date. It is generally used to calculate date, such as Due Date or the next date for recurring job (Job Queue, Recurring Journals, etc).

- C: Current (end of)
- D: Day
- W: Week
- WD: Week Day (not work day). Week Day 1 is Monday.
- M: Month
- Q: Quarter
- Y: Year
Let’s take a look at some examples on what you can do with it.

For developer who use DateFormula with CalcDate, make sure to use < > delimiters surrounding it (example: <1W> ), so the date formula is stored in a generic, nonlanguage-dependent format. This makes it possible to develop date formulas that are not dependent on the currently selected language.
