The year() function returns an integer (number) that corresponds to the year of its date argument.
year(date)
year() (and its sibling functions minute, hour, day, date, and month) is useful for manipulating dates within Notion formulas.
Example Formulas
year(now()) // Output: 2022 (When now() = June 24, 2022)
// Assume a property called Date with a current date of June 24, 2022
year(prop("Date")) // Output: 2022
year() can be used with other functions such as dateSubtract to change the value of a date, like so:
// Assume the value of now() is June 24, 2022
dateSubtract(now(), 10, "years")
// Output: June 24, 2012
You can take this concept even further to “hard-code” any date into a Notion formula. See the section on Hard-Coding Dates into Formulas within the now article for more on how to do this.
Example Database
The now formula example shows how to “hard-code” a date into a Notion formula without a specific year. The example database below does the same thing, except it allows you to specify a year using a Number property.

This formula works the same way as the formula in the now article, except we’re now adding one extra instance of dateAdd and dateSubtract. These final instances:
- Use
year()to take the current year and set it to 0. - Then add the specified year in the Year property.
