Getting started
The problem this solves
Jira automation can add days to a date. It cannot add working days that skip your public holidays.
Automation does understand business days — {{now.plusBusinessDays(5)}} skips
Saturday and Sunday. What it does not know is that your team is closed on 25
December, or that your Gulf office works Sunday to Thursday. There is an open
request for this, AUTO-971, and until
it ships, a rule that promises "resolve within five working days" quietly lands on
Christmas Day.
What you can do without this app, for free
Before you buy anything, know the free options:
plusBusinessDaysis free and built in. If your team works Monday to Friday and you genuinely do not care about public holidays, use it. It costs nothing and it is one smart value.- Jira Service Management SLAs support custom calendars with holiday exclusions. If your deadlines are SLAs on a service project, that is the right tool and it is already included in your licence.
- A hand-maintained lookup in a rule — a long chain of conditions checking for specific dates — works for a handful of holidays a year. It is tedious and it goes stale, but it is free.
If one of those fits, use it. This app exists for the case where none of them do: you need holiday-aware working days inside ordinary automation rules, on ordinary projects, without hand-maintaining anything.
What this app adds
Three actions you can drop into any automation rule:
| Action | Answers |
|---|---|
| Calculate Working Date | "Five working days from today is what date?" |
| Check Working Day | "Is this a working day? When is the next one?" |
| Count Working Days | "How many working days between these two dates?" |
They calculate and return a value. They do not write to Jira — the native Edit work item step does that, which is why the app asks for no Jira permissions at all.
Set-up, in three steps
1. Create a calendar
In Jira, go to Settings → Apps → Working Days, then Create calendar.
Give it a name you will recognise inside a rule — Norway Support, not
Calendar 2. Tick the days your team works. Paste your holidays, one per line:
2026-12-24
2026-12-25
2027-01-01
Full detail: Create a working calendar.
2. Add the action to a rule
Project settings → Automation → Create rule. Pick your trigger, then add Calculate Working Date. Choose your calendar, set a start date, and enter how many working days to add.
The first time you add the action, Jira asks you to connect it. You will see "Before you can use this step, you must connect Atlassian Automation to Working Days" with a Connect button. Click it. This is Jira's own consent step, it happens once, and it grants nothing beyond letting your rule call the action — the app holds no Jira permissions at all.
3. Write the answer somewhere
Add an Edit work item step after it. Set Due date to the smart value the action produced — the rule builder offers it in autocomplete.
That is the whole product.
The one thing that causes confusion
The start date counts as day 0. One working day from a Monday is the Tuesday. Five working days from a Monday is the following Monday.
If your organisation counts the start date as day 1 — so "three working days" starting Monday ends on Wednesday — enter one fewer.
