Frequently Asked Questions

How accurate is the countdown?

The calculator uses your device’s system clock and updates every second. Accuracy depends on your device time synchronization (usually within ±1 second of atomic time if using NTP).

Can I use this offline?

Yes! The calculator is a Progressive Web App (PWA) at its core. Once loaded, it works without internet. Service worker support can be added for full offline functionality.

Does it track my data?

No. All calculations happen client-side. No cookies, no analytics, no data collection. The tool is GDPR/CCPA compliant by design.

Why does my week start option reset on refresh?

The calculator respects browser privacy and doesn’t use localStorage by default. To persist settings, add ?weekStart=sunday to the URL or modify the JS to use localStorage (instructions in code comments).

Can I embed this in my Notion page?

Absolutely! Paste the HTML into Notion’s “Embed” block. The responsive design auto-adjusts to Notion’s column width.

What time zone does it use?

It automatically uses your device’s local time zone. For UTC calculations, modify the Date objects in the JavaScript.

Is there a dark mode?

The current version is optimized for light mode to meet your specific requirements. The CSS can be easily adapted with a prefers-color-scheme media query.

Can I customize the colors?

Yes! Modify the CSS custom properties at the top of the <style> section. Change --primary-color to match your brand.

Why is TikTok not in the share options?

TikTok doesn’t support web sharing URLs. We include a placeholder with instructions for manual sharing.

The calculator shows “–” values. What’s wrong?

This indicates a JavaScript error. Check your browser’s console (F12 → Console). 99% of issues are caused by plugin conflicts in WordPress. The IIFE wrapper prevents most conflicts.
