Frequently Asked Questions
Is my data sent to a server when using the Date Range Calculator?
No. The Date Range Calculator is a fully client-side utility. All data processing, calculations, and conversions are handled locally in your browser. No input text, payloads, or keys are uploaded to any external server.
How is the text comparison calculated?
The comparison runs a fast client-side diff algorithm (like the Myers Diff algorithm) to compute insertions and deletions, highlighting differences inline or side-by-side.
Does it support comparing large files?
Yes, you can paste large text files or script files. Since calculations are done in-memory, comparisons of scripts up to 2MB are computed in milliseconds.
Can I export the diff comparison results?
Yes, you can copy individual change blocks or use standard screenshot utilities to capture the highlighted inline or side-by-side differences.
Does the Date Range Calculator store history or cache my inputs?
No. The application runs entirely in browser memory. Once you refresh the tab, navigate away, or close the window, all inputted details, logs, and outputs are completely cleared.
Is the Date Range Calculator compatible with mobile devices?
Yes. The interface is optimized to be fully responsive. You can perform calculations, conversions, and formats on all modern mobile, tablet, and desktop web browsers.
Does the Date Range Calculator work offline?
Yes. Once loaded, all code and assets required to run the Date Range Calculator reside in your browser cache, enabling offline use without an active network connection.
