The planning time for a company anniversary depends on its size and complexity. For a small anniversary (20–50 people), you’ll need at least 3 to 4 months. For a medium-sized to large anniversary, we recommend 6 to 9 months of preparation.
For a major anniversary (100 years, multiple target audiences, full-scale production), a planning period of 9 to 12 months is no luxury. Popular venues and entertainment options are often booked solid months in advance.
Starting early gives you more creative freedom, greater certainty in planning, and better availability of venues and vendors.
