Zapaday is a free global events calendar you can tap into to find out what's happening soon, from holidays to cultural events and news. Zapaday scrapes 4000+ news sites for future events and also pulls in important public calendars.
The web app, now in beta, can be accessed without signing up for an account, but if you register you can get event notifications for categories that matter to you (business, culture, sports, science and so on).
To stay up-to-date, you can browse by event category and then subscribe to iCal feeds in Google Calendar, Outlook and other calendar apps. Alternatively, save individual events to your Zapaday calendar (which you can subscribe to in your calendar app).
If you need to monitor what's happening (or going to happen) around the world or for a given topic, bookmark — or connect to — Zapaday. It's a comprehensive calendar for upcoming holidays, product launches, conferences and more.
