Bulk calculate product expiration dates in days, months, or years. Perfect for inventory management and expiry tracking.
Adds a positive whole-number duration to a production date; month ends follow calendar month addition. Status is date arithmetic, not food/drug safety, opened-product life or legal validity. Records stay in this browser; export your own backup.

Overview
Understand what the tool solves, how it works, and the boundaries of its data.
This calculator adds a duration you provide to a product’s production date: calculated date = production date + shelf life. Choose days, months, or years; months and years are calendar units, not fixed day counts. For example, May 20, 2024 plus 90 days is August 18, 2024.
Each row shows the product, production date, entered duration, calculated date, days remaining, and status. Rows sort from the fewest days remaining upward. No product or label database supplies the shelf life; you enter it.
Remaining days are the calendar-day difference between the calculated date and today. Negative means Expired. Zero through the configured warning threshold means Nearing Expiry; a larger number means Good. The default threshold is 30 days. Changing it changes status, not the calculated date.
This list organizes supplied dates; it does not identify a product, read barcodes, or determine an official label date. U.S. food labels use varied phrases, and a date may refer to quality. The FDA’s food date guidance explains this distinction.
Use the unit shown by your source: three months and 90 days are different durations.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Use product name, production date, shelf-life value, and unit, in that order. The first worksheet is read, its first row is skipped as a header, and later rows are mapped by position. The sample workbook shows the layout.
Upload XLSX, XLS, or CSV, or use manual entry for one product. Select days, months, or years. Incomplete or unrecognized rows may be skipped.
Inspect names, dates, units, and sorted results. Adjust the warning threshold in Settings to match your planning window. Export Data downloads the current list as CSV with the input fields, calculated date, remaining days, and status.
Use cases
See how the tool fits into real work and everyday tasks.
Import a batch sheet and start with the rows showing the fewest days remaining. Verify each against the stock record and package.
Keep a working list of products with known dates, then export the sorted rows for the shop’s own recordkeeping process.
Record reliable product information and use the list to decide what to inspect first. Follow package storage directions.
Q&A
Find concise answers to common questions and confusing cases.
No. Months add calendar months; days add the exact number entered, so results can differ.
Zero remaining days is included in the warning range, along with positive counts up to the chosen threshold.
The first worksheet is used. After skipping its first row, the tool expects name, production date, duration, and unit in that order.
No. It adds your duration to your date and organizes the results; it does not check storage, labels, or food safety.
Notes
Review scope, result limitations, and important precautions before use.
A calculated date only reflects your input. It does not validate shelf life, account for storage conditions, or establish whether food, medicine, cosmetics, or another product is safe to use. Food label terms and requirements can vary; check the package, manufacturer, and applicable official guidance. Ask the manufacturer or a qualified professional about product-specific questions.
The list and settings are retained in browser storage on the current browser. On a shared device, remove records when no longer needed. Save exported CSV files according to your recordkeeping needs.
