What is an internal communications calendar?
An internal communications calendar is the yearly plan of the moments when a company speaks to its people. It combines two kinds of dates. The first are specific to the company: seminars, results, launches, annual reviews. The second are shared by everyone: international days, holidays, major sporting or charity events.
Dates that come back every year at the same time are often called awareness days or seasonal moments. They give you a natural reason to talk about an important topic. World Mental Health Day, for example, is a good moment to open a conversation about workload, and Breast Cancer Awareness Month (Pink October) to talk about prevention.
An HR calendar, a CSR calendar and a wellbeing calendar are versions of the same tool. Each one keeps the dates that serve its priorities. This 2027 calendar brings them together, with a theme marker for every date.
How to build your 2027 internal communications calendar
Here is the method we recommend to the teams we work with, in five steps.
Example: one month of your calendar template
Here is what one line of your calendar can look like, for March 2027:
- Date: Monday 8 March 2027, International Women's Day.
- Goal: show what the company does for gender equality at work.
- Format: a two-week team challenge and a discussion session with managers.
- Audience: all teams, on site and remote.
- Channels: intranet, manager messages, employee engagement app.
- Owner and deadline: the HR team, preparation starting at the end of January.

The trends that will shape 2027
1. Mental health stays a priority
Companies are looking for actions that last beyond a single campaign. Blue Monday (18 January), World Sleep Day (19 March) and World Mental Health Day (10 October) are three moments to keep the topic alive through the year.
Our advice: link these dates with a common thread. Our article on mental health at work gives practical ideas.
2. Inclusion needs visible action
International Women's Day in March and the International Day of Persons with Disabilities in December are two key inclusion moments. Employees expect actions they can join. The H-GAMES, our inter-company competition for disability inclusion, are designed for that.
3. CSR is lived every day
Environmental and solidarity days (Earth Day, World Cleanup Day, Giving Tuesday, International Volunteer Day) are a chance to move from words to action, with initiatives everyone can take part in. Our 10 ideas for solidarity actions can help you get started.
What's inside the 2027 calendar PDF

- concrete event ideas, to run in the office or remotely;
- 4 key moments with their own page: Pink October (Breast Cancer Awareness Month), the H-GAMES, Movember and the Advent calendar;
- an always up-to-date version: the calendar keeps growing as we launch new campaigns.
