ToolMagic's calculator collection covers everyday math and utility needs. From date calculations to barcode generation, these tools provide instant, accurate results right in your browser.

Date & Age Calculators

The date duration calculator finds the exact number of days, weeks, months, and years between any two dates. Add or subtract days from a date to plan deadlines, project timelines, and milestones. The age calculator computes your exact age in years, months, and days, displays your zodiac sign, and counts down to your next birthday.

Utility Tools

The archive extractor opens ZIP files directly in your browser — view the file listing, download individual files, or extract everything at once. No server upload means your files stay private and there's no size limit. The barcode generator creates Code 128, Code 39, EAN-13, EAN-8, and UPC-A barcodes that you can download as PNG or SVG files for labels, inventory systems, and product packaging.

Agricultural Calculators

The corn yield calculator estimates bushels per acre from ear count, kernel rows, kernels per row, and row spacing measurements. Moisture adjustment ensures accurate yield projections for harvest planning and crop insurance estimates.

Every calculator runs client-side with no data collection. Results are instant and your inputs never leave your device.
