30 Boxes

30 Boxes Calendar (Month View).

What We Like

  • Supports plain language entries.

  • Schedule recurring events.

  • Colored tags for emphasis and organization.

  • Share all, part, or none of the calendar.

What We Don't Like

  • Limited to a one month view of activities at a time.

  • Doesn't warn if two events are scheduled at the same time.

  • Bare-bones website doesn't provide much information before you register.

The 30 Boxes calendar has a simple design that lets anyone create and use an online calendar easily.

Create events with a click and add notes, text or email reminders, repeating events, and invites. There's also a to-do list that's not part of the calendar so that you can fill it with things you need to get done but don't want to define a date for.

Events can be structured so you see them by week or in a list with agenda view. There's also a view that shows a map of all your events that have a location attached to them.

If you like to get daily email summaries of your online calendar events, 30 Boxes lets you do that, too.

Something else worth mentioning about this online calendar is that when you add events, you can add the same event to multiple days at once by picking dates on the calendar, something you can't even do with some of the more popular online calendar websites.

You can share the calendar with others via RSS, iCal, a read-only web page, or even through your own website with embeddable HTML code. You can also print the calendar in the week, agenda, or month view.

Easily add events to the calendar with specific colors and text. You can change the view to see every entry in week, month, or year view.

There's also a portable, downloadable program that can be run from your desktop to access your calendar without ever opening a web page. Everything you change in this program is reflected in your calendar online when you next go online.

There's also an option to embed your calendar in a web page so you can add your public calendar to your blog.
