What it helps you decide
Build customer and internal dates from validated shelf life.
Free shelf-life date planner
Turn one production date into the dates your team needs.
Use your already validated shelf-life period to calculate a customer-facing best-by date, an earlier internal pull date, and a reminder date for review or discounting.

Date inputs
Plan a batch timeline
This planner performs date math only. It does not determine product safety or establish shelf life; use a period supported by your process, testing, and applicable guidance.
A simple operating habit
Keep customer dates and internal action dates separate.
Your best-by date can remain the customer-facing quality date while the internal pull date creates room to inspect, discount, donate, or remove stock according to your own documented policy.

How to use the Best-By Date Planner
Build customer and internal dates from validated shelf life. The calculator runs privately in your browser and is designed to make the assumptions behind the answer visible.
What to have ready
Measure the actual product and inside pack dimensions, confirm weights, quantities, material limits, and any carrier or printing requirements.
How to use the result
Use the result to shortlist a pack or create test artwork, then verify it with a physical fit, print, drop, transit, or shelf-life test as appropriate.
Complete workflow guide
Inventory and traceability
A stock count tells you how much is on the shelf. Traceability explains how it arrived, which batch used it, and which customers received the finished product.
