# Rainlendar

> Skinnable desktop calendar for Windows, Mac and Linux

Rainlendar is a desktop calendar for Windows, Mac and Linux that keeps events and tasks in small windows on the desktop. Data is stored locally in the standard iCalendar format, the appearance is changed with skins, and Lua scripts can extend what the windows do. The Lite version is free; a one-time Pro license adds sync with Google Calendar, Outlook, CalDAV and other services, plus CSV import and export.

## Ways to pay less

- **Lifetime Pro license with free upgrades** (Lifetime license): The purchase page describes Pro as a single purchase of a lifetime license. The homepage says existing license holders upgrade for free, and the FAQ says one license covers one user on several computers. Source: https://www.rainlendar.net/purchase

## Key features

- **Events and tasks on the desktop:** Events and tasks are kept in separate lists that sit on the desktop, and both can also be shown in the calendar window. Several windows can be shown at once, such as the current and the upcoming month.
- **Alarms with snooze:** An alarm can fire ahead of an event or task and be snoozed for later. A single event or task can carry more than one alarm.
- **Skins and Lua scripting:** Skins change how the windows look and can be mixed together, categories change how individual events appear, and Lua scripts can alter how a skin behaves or fetch content from the internet.
- **Standard iCalendar storage:** Events and tasks are saved in the iCalendar format (RFC 2445), by default in a local .ics file, and can be exported or imported as .ics. Settings and events are backed up automatically every day.
- **Sync with online calendars (Pro):** Pro connects to Google Calendar and Tasks, Office 365 / Outlook.com, CalDAV servers, network shared calendars, Remember The Milk and Toodledo, and to Microsoft Outlook on Windows.
- **Quick Add and printing:** A Quick Add widget creates an event or task from one line of text, including a recurrence pattern and a category. Events and tasks can be printed as a list or a calendar layout, or written to a PDF.

## Good for

- People who want upcoming events and tasks always visible on the desktop
- Households or offices that mix Windows, Mac and Linux computers
- Users who like to restyle an app with skins and scripts
- Buyers who prefer a small one-time payment to a subscription

## Worth knowing

- No mobile or web version. The site suggests syncing both Rainlendar Pro and a phone with Google Calendar instead.
- Sync with Google, Outlook.com, CalDAV and the other online services is limited to Pro, and Outlook support is Windows only.
- The Pro license is sold in euros, at 9.95 EUR; the purchase page shows no US dollar price.
- Rainlendar does not merge calendars from different sources; each stays a separate calendar shown in the same window.
