Holiday calendars
Holiday calendars define the public holidays that apply to your employees. When a day is marked as a holiday, the employee’s expected work time is reduced or canceled for that day, which is reflected in balances, reports, and payroll exports.
Overview
Each holiday calendar contains one or more plugins, each contributing a set of holiday dates for a given year. mTime includes built-in plugins for Danish and French national holidays, a generic Christian holidays plugin, and a custom days plugin for manually defined dates.
Calendars are applied to employees through a resolution chain — from the most general to the most specific. The workspace default applies to everyone, but individual org units and employment terms can each specify a different calendar, giving you fine-grained control over which holidays apply to which teams or contract types.
Managing holiday calendars
Go to to view all holiday calendars in your workspace.
Each row in the list shows the calendar’s name, description, and the number of holidays it generates for the current year. The Default badge identifies the workspace default calendar.
From the action menu on any row, you can:
- Edit — Open the calendar configuration
- Make Default — Set this calendar as the workspace default
- Copy — Duplicate the calendar with all its plugins
- Delete — Permanently remove the calendar
Creating a holiday calendar
- Go to
- Click Add Calendar
- Enter a Name and an optional Description
- Under Configuration, add one or more plugins to define which holidays are included
- Review the resolved holidays for the current year in the Preview section
- Click Save
The first calendar you create is automatically set as the workspace default.
Plugins
A holiday calendar can include multiple plugins. Each plugin contributes its own set of holiday dates, and any duplicates across plugins are merged automatically.
Danish Holidays
Generates standard Danish public holidays for each year. Individual holidays can be enabled or disabled — for example, you can include Labour Day (1 May) or New Year’s Eve only if they are relevant to your organization.
French Holidays
Generates standard French public holidays, including Bastille Day, Assumption of Mary, and Armistice Day. The Good Friday option is available for organizations in Alsace-Moselle.
Christian Holidays
A flexible set of Christian holidays not tied to a specific country. Use this plugin when your country is not covered by a built-in national plugin. You can choose from Easter, Ascension Day, Whit Monday, Christmas Day, Boxing Day, and more.
Custom Days
Define your own one-off or recurring holidays manually. Each custom day includes:
- Name — A label for the holiday (e.g., “Company Day”)
- Date — The specific date
- Recurring — When enabled, the holiday repeats every year on the same day and month
- Type — Controls expected work time on that day:
- (none) — Full holiday: expected work time is set to zero
- Factor — Partial holiday as a percentage of normal hours (e.g., 50 for a half-day)
- Expected minutes — A fixed expected work duration for the day
Preview
The Preview section shows all resolved holidays for the current year, based on the configured plugins. Use it to verify the complete list before saving. Any changes to plugins are immediately reflected in the preview.
Calendar assignment
Holiday calendars are resolved in the following order, from lowest to highest priority:
- Workspace default — The fallback calendar that applies to all employees. Set it by opening the action menu for any calendar and selecting Make Default .
- Organization unit — You can assign a calendar to any org unit in . Employees in that unit will use it instead of the workspace default. If an org unit has no calendar set, mTime looks up the hierarchy to the parent unit, and so on, until it finds one.
- Employment terms — The highest-priority override. A calendar assigned to employment terms in applies to all employees on those terms, regardless of their org unit.
The most specific setting always wins: employment terms take priority over the org unit, which takes priority over the workspace default.
