Math Calculus

Expression	Returned Value	Notes
`max(count(subtasks(%{00041})) - 1, 0)` or since version 2.2.1: `count(siblingSubtasks())`	For a sub-task, the number of sibling sub-tasks.	Function `max(x, y)` is used to avoid returning `-1` when used with non-sub-task issues. `%{00041}` = Parent's issue key
`{10000} = null ? 1 : {10000} + 1`	Formula to increment a numeric custom field, setting it to `1` if it's initially unset.	`{10000}` is the field code for a supposed numeric custom field.
`{10000} + {10001} + {10003}`	Formula for summing 3 numeric custom fields when we are certain that all 3 the fields are initialized. In case any of these fields is not initialized, an error is raised and any of the following 2 expression examples should be used.	`{10000}`, `{10001}` and `{10003}` are three numeric custom field.
`({10000} = null ? 0 : {10000}) + ({10001} = null ? 0 : {10001}) + ({10003} = null ? 0 : {10003})`	Formula for summing 3 numeric custom fields when some of them may be uninitialized. When any of this fields is not initialized a zero value is assumed.	`{10000}`, `{10001}` and `{10003}` are three numeric custom field.
`sum([{10000}, {10001}, {10003}])`	A more compact syntax for summing 3 numeric custom fields when some of them may be uninitialized. Version 2.2.16 or higher is required.	`{10000}`, `{10001}` and `{10003}` are three numeric custom field. This syntax is available since version 2.2.16.

Date-Time Calculus

Expression	Returned Value	Notes
*`{00012} - 6 {DAY}`**	Calculates a date 6 natural days earlier than Due Date	`{00012}` = Due Date

*`addTimeSkippingWeekends({00009}, 36{HOUR} + 45{MINUTE}, LOCAL, {FRIDAY}, {SATURDAY})`*	Same as previous expression, but using Israeli weekend.	Israeli weekend is on Friday and Saturday.
`addDaysSkippingWeekends({00012}, -6, LOCAL)`	Calculates a date 6 work days earlier than Due Date for Jira Server's local timezone.	`{00012}` = Due Date Work days depend on timezone, since certain time moment maybe Sunday in certain time zones, and Monday in another ones.
`subtractDatesSkippingWeekends({00012}, {00057}, LOCAL)/{DAY}`	Returns the number of working days from Current Date and Time to Due Date, i.e., skipping weekends in Jira server's timezone.	`{00012}` = Due Date `{00057}` = Current day and time
`round(({00057} - {00009}) / {HOUR})`	Number of hours since issue creation	Function `round()` approximates the number of hours to the nearer integer. `{00057}` = Current day and time `%{00009}` = Date and time of creation
`floor(({00012} - {00057}) / {DAY})`	Number of days to Due Date	Function `floor()` approximates the number of days by removing the fractional part. `{00012}` = Due Date `{00057}` = Current day and time
*`datePart({00057}, LOCAL) + (dayOfTheWeek({00057}, LOCAL) = 7 ? 6 : 6 - dayOfTheWeek({00057}, LOCAL)) {DAY}`**	Returns a date value for next Friday, or for today if it's Friday	`{00057}` = Current day and time Example
*`datePart({00057}, LOCAL) + (dayOfTheWeek({00057}, LOCAL) = 6 ? 7 : (dayOfTheWeek({00057}, LOCAL) = 7 ? 6 : 6 - dayOfTheWeek({00057}, LOCAL))) {DAY}`**	Returns a date value for next Friday, even if today is Friday.	`{00057}` = Current day and time Example
`floor(subtractDatesSkippingWeekends({00057}, {00009}, LOCAL) / {DAY}) + " days " + floor(modulus(subtractDatesSkippingWeekends({00057}, {00009}, LOCAL), {DAY}) / {HOUR}) + " hours " + round(modulus(subtractDatesSkippingWeekends({00057}, {00009}, LOCAL), {HOUR}) / {MINUTE}) + " minutes"`	Calculates the time since issue creation skipping weekends, and shows it as a text like this: 12 days 6 hours 34 minutes.	`{00057}` = Current day and time `%{00009}` = Date and time of creation
`floor(({00057} - {00009}) / {DAY}) + " days " + floor(modulus(({00057} - {00009}), {DAY}) / {HOUR}) + " hours " + round(modulus(({00057} - {00009}), {HOUR}) / {MINUTE}) + " minutes"`	Calculates the time since issue creation, and shows it as a text like this: 12 days 6 hours 34 minutes.	`{00057}` = Current day and time `%{00009}` = Date and time of creation

Issue Selection

Expression	Returned Value	Notes
`filterByFieldValue(subtasks(), %{00094}, ~ , "Component A")` or alternatively `filterByPredicate(subtasks(), %{00094} ~ "Component A")`	Returns an issue list with sub-tasks having "Component A" among its components.	`%{00094}` = Components

`{00012} > max(fieldValue({00012}, union(linkedIssues("is blocked by"), subtasks())))`	Validation to check that: Due Date is greater than latest Due Date among blocking issues and sub-tasks.	Function max(number_list) is available since version 2.1.22 `{00012}` = Due Date
`count(filterByFieldValue(subtasks(), %{00070}, =, "") UNION filterByFieldValue(subtasks(), %{00012}, =, "")) = 0` or alternatively `count(filterByPredicate(subtasks(), ^%{00070} = null OR ^%{00012} = null)) = 0`	Expression for checking whether all sub-tasks of current issue have fields Due date and Environment set.	`%{00012}` = Due date `%{00070}` = Environment
`count(filterByPredicate(linkedIssues("is Epic of"), ^%{00028} != null OR ^{00012} = null)) = 0`	This validation allows certain transition in Epic's workflow to be executed, only if all the tasks are unresolved and have Due Date set.	`^%{00028}` = Resolution in foreign issues `^{00012}` = Due Date in foreign issues. Example

Logical Constructions

Expression	Returned Value	Notes
`!(%{00017} = "Blocker" OR %{00017} = "Critical") OR {00012} != null`	Validation for checking that: If Priority is "Blocker" or "Critical" then Due Date must be initialized.	It is based on equivalent logical constructions: A implies B = !A OR B `%{00017}` = Priority `{00012}` = Due Date
`%{00017} = "Blocker" OR %{00017} = "Critical" IMPLIES {00012} != null`	Validation for checking that: If Priority is "Blocker" or "Critical" then Due Date must be initialized.	Same as former example but using logical connective IMPLIES, which is available since version 2.1.22. `%{00017}` = Priority `{00012}` = Due Date
*`{00012} = null OR {00012} >= ({00009} + 2 {DAY})`**	Validation for checking: If Due Date is set then it must be equal or grater than Day and Time of Creation plus 2 days.	`{00012}` = Due Date `{00009}` = Date and time of creation

Boolean Expression examples

Boolean expressions are logical constructions that return true or false, and are used for implementing conditions, validations, and conditional executed post-functions.
