Rainlendar是一个简单实在的桌面日历，当然界面也是比较漂亮的。只占少量系统资源，可以设置未透明效果，内含有两个模板可选择，当然可以上作者官网下载更多漂亮模板。没有太多烦琐的设置，你可以设置它的4种位置方式（总在最前，总在最后，普通窗口和钉在桌面上），当然Rainlendar也像其他桌面日历一样，有个非常不错的事件提示功能，防止有重要事情由于在看电影或游戏中而错过。提醒功能分为新事件和新计划，另外还可以自己个性定义显示的内容。需要桌面日历和比较容易健忘“重要事情”的网友可以试试这个。 虽说是个轻量级软件，但却是麻雀虽小五脏俱全。可以这么概括一下 Rainlendar：黑莓的日历 + 任务，相信黑莓用户只要对 GTD 要求不高的话对黑莓自带的日历和任务功能应该是很满意的（何况还可以与 Google Calendar、Facebook、Remember the Milk 等同步）。Rainlendar 的在日历和任务方面的功能可以说和黑莓的日历、任务是一样的，简单好用也很实用。
Rainlendar is a customizable calendar application which stays out of your way but keeps all your important events and tasks always visible on your desktop. Rainlendar Pro is a calendar with plenty of tools that are easy to use. It lets you set up events and to-do tasks that can be viewed straight from the desktop.
Events and Tasks
Rainlendar supports events and tasks which both are kept in separate lists. This helps you to keep your life better organized and makes it easier to see what are the upcoming things you need to do.
Get notified in advanced before the event is due so that you don't forget your important events. It is also possible to snooze the alarm if you want to get reminded about it later.
All the data is stored in the standard iCalendar format (RFC2445) which is supported by most calendar applications. This makes it easy to transfer the events between applications.
The look and feel of the calendar can be changed with skins. You can also mix the skins together and have as many windows visible as you want.
Rainlendar has been translated to over 50 different languages so you can use it in your native language. It's also possible to use any language when entering the events.
The application works in all major operating systems: Windows, Mac OS X and Linux. All the data, skins, languages and scripts are the same in all platforms so you can easily migrate between them.
Shared & 3rd Party Calendars
With Rainlendar Pro you can subscribe to online calendars and share your events with other computers. You can also see and edit your Outlook appointments and tasks in Rainlendar (Windows only).
What's new in version 2.13.1 Build 147:
- Weekly recurring tasks did not show due date correctly if the interval was greater than 1.
- '!'-char broke the links.
- Using %W in time items moved the time to the first day of the week.
- The current language is now stored as a string to settings so that it doesn't accidentally change when upgrading to new version.
- The tooltip is opened always upwards if there is more room.
- Changing months from keyboard works only if no modifiers (shift, alt, control) are down.
- Added check to prevent redraw loop in task and event lists.
