By using the site you agree to these terms. If you do not agree, do not use it.
Service
We provide tools and calculators for personal, non-commercial use without a visitor account. Most calculations run locally; some features use our server and external APIs.
Accuracy
Results are provided as is for general and educational purposes, without a warranty of accuracy, completeness or fitness for a particular purpose. Verify the input, interpretation and result before relying on them. Results are not financial, medical, legal or professional advice.
Time and working-hours disclaimer
1pm to 7pm is 6 hours. The calculation does not deduct breaks or calculate pay or payable working hours. Both times are assumed to be in the same time zone. An earlier end time is treated as the following day. Equal times mean zero hours unless the following day is selected. Date differences and daylight-saving changes are not included. Use exact dates, time zones and applicable work rules where needed.
AI interpretation
AI may misunderstand dialects or produce incorrect or incomplete interpretations. Check the displayed interpretation and do not rely on an unclear result. AI is used only when enabled, local parsing fails and you press Convert. Do not include sensitive information in your phrase. See the privacy policy for OpenRouter processing and request-log retention.
External services and limits
Some features use OpenRouter, model providers or external calendar services. Availability, speed and continued free-model access are not guaranteed. Request limits, errors and model changes may occur. If AI is unavailable, use numbers or locally supported phrases; not every phrase can be converted.
Acceptable use
Do not attempt unauthorized access, harm the site, bypass request limits, or use the duration AI endpoint for general chat or unrelated purposes. Automated scraping at scale requires permission.
Intellectual property
The design and editorial content are protected by intellectual property rights. Republishing requires permission, except personal use or ordinary quotation with attribution.
Liability and rights
To the extent permitted by applicable law, we are not responsible for losses arising from reliance on tool results. These terms do not exclude mandatory rights that cannot lawfully be excluded.
Changes and contact
Updates are published here. Applicable law governs these terms without prejudice to mandatory rights. Contact us through the contact page with questions.
