Questions, feedback, or bug reports — we read everything
Use the form below to send us a message. We welcome feedback on existing tools, suggestions for new features, bug reports, and general questions about the site or its calculations.
Are the calculations accurate?
Yes, for amateur astronomy and educational purposes. All
tools use established astronomical algorithms. For professional or navigation-grade precision, consult the JPL
Horizons system.
Why do sunrise times not match my clock?
The tool calculates solar time based on your
longitude. To convert to clock time, add your UTC offset and account for daylight saving time if applicable.
Can I use linkvane offline?
Yes. Once the page is loaded in your browser, all tools work
without an internet connection because everything runs locally.
Will you add more tools?
We plan to expand the toolkit over time. Use the contact form to
suggest tools you would find useful.
