Absence calendar: definition, template and implementation in Microsoft 365
An absence calendar shows vacation and other absences across the team at a glance. As soon as several departments or locations are involved, Excel lists and email coordination quickly reach their limits.
Absence calendar: the essentials at a glance
- An absence calendar maps vacation, sickness and other time away for the whole team and makes cover arrangements visible at a glance.
- Excel templates work as a starting point for an absence calendar, but from about five to ten employees the maintenance effort and error risk rise quickly.
- The General Data Protection Regulation requires appropriate technical and organisational measures for an absence calendar — for example role-based access, secure transmission and traceable documentation.
- absentify maps the absence calendar directly in Microsoft Teams and Outlook, so companies can work without an extra platform outside Microsoft 365.
What is an absence calendar?
An absence calendar lists planned and approved absences as well as reported time away for a team in one shared overview — usually as a day or week view with names, period and absence type. Some companies also call this overview an absence list or time-away calendar.
Typical entries are vacation, sickness, training and business travel. Some companies keep the calendar separate from pure vacation planning; others combine both views in a vacation calendar. The difference is scope: a vacation calendar only shows vacation days, while an absence calendar also covers sickness, parental leave and other reasons for time away.
How do you set up an absence calendar template in Google Sheets?
The free absence calendar template from absentify in Google Sheets maps vacation and sickness for the whole team in one shared sheet once every employee has edit access.
- Sharing: The file must be shared with the entire team via email addresses.
- Edit rights: Without protected ranges, anyone with edit rights can change the sheet. If protection is set incorrectly, nobody can enter anything.
- Team coordination: Entries should only be made after other employees’ absences have been checked, because Google Sheets does not automatically validate leave quotas or overlaps.
absentify sets absence quotas and approves requests directly in Microsoft Teams and Outlook, so nobody has to switch between multiple tools.
What problems arise with an absence calendar in Excel?
A free Excel template for an absence calendar works for a first start, but as teams grow it leads to duplicate entries, outdated versions and missing auditability.
The file must be shared with the whole team so every employee can enter their own days. Without protected ranges, anyone with edit rights can change formulas and other people’s entries without those changes being reliably logged. In internal reviews or employment-law queries it is then hard to prove who requested and approved which leave when.
From about five to ten employees, maintenance effort rises noticeably. Remaining leave must be calculated manually, public holidays by federal state are often missing, and sick notes often reach HR only by email or phone.
How do you map an absence calendar in Microsoft Teams and Outlook?
Absences can be mapped in Microsoft Teams and Outlook by employees setting their status manually, maintaining calendar entries, or using an add-on that syncs the entries.
What do Teams and Outlook offer without add-on software?
Native Teams presence mainly shows the current status such as “Away” or “Available”, but not a full calendar overview of upcoming vacation days. Setup differs by product: you configure absences in Outlook depending on Outlook version and account type, and you set absence in Teams directly in the client.
How does absentify add a personal calendar to Teams and Outlook?
absentify adds a personal absence calendar to both products, syncs accounts automatically via Microsoft Entra ID and makes remaining leave visible, so nobody has to switch platforms. When an employee leaves the company, absentify removes the account from all absence overviews automatically — without manual clean-up.

Which legal and data-protection duties apply to an absence calendar?
An absence calendar must meet General Data Protection Regulation requirements as soon as it contains health data such as sick notes or information about a severe disability, because these fall into a special protection category.
Access should only go to people who need the data for their role — for example the direct manager and HR. Changes to entries should later be attributable to a person and a point in time, which is often only partly possible in simple shared Excel files.
What applies to company shutdowns?
If a company also schedules a company shutdown, Germany’s Federal Vacation Act (BUrlG) applies. Employers may not use plant holidays to schedule the entire annual leave entitlement and must leave employees a sufficient share to use freely. A properly configured absence calendar with an approval workflow can document such rules, including timestamps and approvers.
What cooperation duty applies in case of sickness?
In case of sickness, the notification and proof duties from Germany’s Continued Remuneration Act (EntgFG) apply. Employees must report incapacity for work without delay; employers may document required proof and sick-note data in a legally sound way. A manually maintained absence calendar rarely maps this reporting chain completely, because sick notes often arrive by phone or chat and are only later copied into the sheet. An automated reporting or documentation workflow can instead record notification time, period and follow-up.
How do you keep an overview when several employees are away at the same time?
A minimum staffing level per department prevents too many employees from being absent in the same period and operational work from stalling.
In Excel, such a rule can only be checked manually: someone has to scan every employee row in a department and mark overlaps by hand. With ten or more people per department, that cross-check becomes time-consuming and error-prone.
absentify groups employees into departments and sets a minimum staffing level for each, so a request is flagged automatically as soon as it would drop below the limit. Approvers already see at request time which colleagues are away in the same period, so bottlenecks can be spotted before approval — not only afterwards.
Excel, native Teams features or absentify: what fits your team?
Small teams of five to ten people can often still manage with a simple Excel template. As soon as several departments, locations or public-holiday rules come together, specialised software becomes the better option.
An everyday example: A company with three locations in different German federal states must plan separate public holidays for each site. In Excel that means several worksheets and manual cross-checks. absentify assigns public-holiday calendars from 250 countries to the right departments automatically.
A second example: A growing team hires new employees every month and must add every new account to the Excel file by hand, including remaining-leave calculation by start date. absentify imports new employees automatically from Microsoft Entra ID and calculates pro-rata remaining leave at creation, so HR does not have to maintain a single entry manually.
How to map absences in a structured way in Microsoft 365
An absence calendar in Excel works for small teams, but hits limits as headcount, locations or GDPR duties grow. Microsoft Teams and Outlook show current status, yet without an add-on there is no calendar overview with remaining leave and an approval workflow. Dedicated vacation planner software closes exactly that gap — without employees having to leave the Microsoft tools they already use.
Your advantages with absentify:
- Personal calendar per employee with automatic remaining-leave calculation
- Automatic sync with Microsoft Entra ID without manual account maintenance
- Public-holiday calendars from 250 countries, assigned to departments and locations
- Approval workflows with timestamps for complete documentation
Automate your leave management in Microsoft Teams
Switch with absentify to automatic remaining-leave calculation and approvals directly in Outlook and Teams. Sign up in a few minutes and end duplicate Excel maintenance for your whole team.

Reducing overtime: rights, duties and the process for employers and teams
Reducing overtime means offsetting accumulated extra hours with time off or payment. Under German employment law, the six calendar months or 24 weeks specified in the German Working Time Act apply solely to offsetting an extended working day against the statutory eight-hour average. Employment contracts, works agreements or collective agreements determine how an overtime balance can be reduced. Where these rules permit time off in lieu, the employer determines its timing and process within the scope of their right to give instructions.

When does unused leave expire? Deadlines and exceptions that determine your entitlement
Under German law, unused leave expires only under certain conditions: entitlement generally lapses on 31 December, or after the carryover period on 31 March, only if your employer has given you timely and specific notice of the impending expiry and you still do not take the leave. An exception applies in cases of continuous illness.

Employee Self Service (ESS): Definition, Features, and Benefits for Leave and Absence Management
Employee Self Service (ESS) gives employees access to manage their personal data, leave requests, or absences themselves without coordinating every step with HR. The term originally comes from SAP HR modules and has become an umbrella term for self-service features in human resources. Its benefits are particularly clear in leave and absence management.
