Frequently Asked Questions
Where are my events saved?
Events are stored in your browser’s local storage on this device only. If you clear site data or switch browsers/devices, they won’t carry over.
How do I add or remove an event?
Click a date, enter a title in the Add event field, and press Add. To remove, click Remove beside the event in the day list.
Can I see multiple events on one day?
Yes. The day panel lists all items for that date, and the calendar cell shows a green dot to indicate you have events there.
Why don’t I see all public holidays?
You’ll see built-in holidays (plus common global days). For full national coverage, add your Calendarific API key in the code. Without an API key, only built-ins are shown.
How are weekends decided?
They follow your selected Country (e.g., Fri–Sat in some countries, Sat–Sun in others). You can also set Week starts to Sunday or Monday.
Does the calendar support reminders or notifications?
Not in this version. For alerts, use the Alarm or Countdown Timer tools on your site.
Will my events sync between devices?
No. This calendar is privacy-first and offline-friendly; it does not sync to a server.
Does it work offline?
Yes, after the page loads. Built-in holidays and your saved events still show. (API-based holiday fetching requires internet.)
Can I export my events?
There’s no one-click export yet. You can copy from the Upcoming this month list, or we can add a CSV/ICS export if you want.
Is it accessible?
Yes—buttons have labels, focus states are visible, and grid cells expose dates via time and ARIA roles for assistive tech.
Can I sync this calendar with other tools?
This tool is browser-based and privacy-focused, so it doesn’t sync with external services — your data stays local.
