bootstrap-datepicker
A datepicker for twitter bootstrap
Bootstrap-datepicker provides a flexible datepicker widget in the Bootstrap style. Versions are incremented according to semver. As with bootstrap’s own plugins, datepicker provides a data-api that can be used to instantiate datepickers without the need for custom javascript. You can disable datepicker’s data-api in the same way as you would disable other bootstrap plugins. Most options can be provided via data-attributes. An option can be converted to a data-attribute by taking its name, replacing each uppercase letter with its lowercase equivalent preceded by a dash, and prepending “data-date-” to the result. Methods are called on a datepicker by calling the datepicker function with a string first argument, followed by any arguments the method takes. -

Lotus Notes to Google Calendar tool
One-way synchronization from Lotus Notes Calendar to Google Calendar
This is a one-way sync program that will sync your Lotus Notes Calendar to your Google Calendar. No installation is required. Includes many options such as automatic syncing at specified intervals. *Important Privacy Information: https://sourceforge.net/p/lntogoogle/wiki/PrivacyPolicy/ *** Information Update, September 2020: *** Recent issues with Google Synchronization should be fixed with version 1.9.2 which is available for download, now. For typical installation pitfalls, see: https://sourceforge.net/p/lntogoogle/wiki/InstallationPitfalls/ The project was not maintained since its last update in February 2015. However, since I've tracked more than 15.000 Downloads over the last 5 years and still more than 1 million Calendar API-Calls per day, I assume that the tool is still very much in use. So I decided to go back to work. More info: https://sourceforge.net/p/lntogoogle/wiki/Home/ Donations appreciated -

Joda-Time
Replacement for the Java date and time classes prior to Java SE 8
The standard date and time classes prior to Java SE 8 are poor. By tackling this problem head-on, Joda-Time became the de facto standard date and time library for Java prior to Java SE 8. Note that from Java SE 8 onwards, users are asked to migrate to java.time (JSR-310) - a core part of the JDK which replaces this project. The design allows for multiple calendar systems, while still providing a simple API. The “default” calendar is the ISO8601 standard which is used by many other standards. The Gregorian, Julian, Buddhist, Coptic, Ethiopic and Islamic calendar systems are also included. Supporting classes include time zone, duration, format and parsing. Joda-Time provides a quality replacement for the Java date and time classes. Joda-Time is the de facto standard date and time library for Java prior to Java SE 8. Users are now asked to migrate to java.time (JSR-310). -

Manage events on a Google Calendar
Manage events on a Google Calendar
This package makes working with a Google Calendar a breeze. Manage events on a Google Calendar. The first thing you’ll need to do is get credentials to use Google's API. I’m assuming that you’ve already created a Google account and are signed in. Head over to Google API console and click "Select a project" in the header. You can give the service account a name. You can name it anything you’d like. In the service account id you’ll see an email address. We’ll use this email address later on in this guide. Select "JSON" as the key type and click "Create" to download the JSON file. You will get a warning that the service account does not have a role, you can safely ignore this and create the service account without assigning a role. Head over to Google Calendar and view the settings of the calendar you want to work with via PHP. On the "Share with specific people" tab press the "Add people" button and add the service account id that was displayed when creating credentials on the API site. -

react-big-calendar
gcal/outlook like calendar component
An events calendar component built for React and made for modern browsers (read: IE10+) and uses flexbox over the classic tables-ception approach. Styles can be found at: react-big-calendar/lib/css/react-big-calendar.css, and should be included on the page with the calendar component. Also make sure that your calendar's container element has a height, or the calendar won't be visible. Date internationalization and localization is hard and react-big-calendar doesn't even attempt to solve that problem. Instead you can use one of the many excellent solutions already out there, via adapters called "localizers". Big Calendar comes with two localizers for use with Globalize.js or Moment.js. Choose the localizer that best suits your needs, or write your own. Whatever you do, you'll need to set it up before you can use the calendar (you only need to set it up once). -

How Users Can Get Started With Open Source Calendar Software
Getting started with open source calendar software is fairly straightforward and can be done in a few easy steps.
The first step is to decide which type of open source calendar you want to use. Popular options include Mozilla Thunderbird, Nextcloud Calendar, and Open-Xchange Calendar. All three platforms have free versions available for download on the web. Researching each one's features and capabilities will help you determine which option best suits your needs.
The next step is to register or sign up for the associated platform account after downloading your desired software package. This registration process ensures that all your data remains securely stored within the system.
Once registered, you'll need to set up accessibilty settings so that other users are able to view shared events or send invitations when necessary. Depending on what platform you're using, this may involve assigning permission levels or creating groups based on who has access to certain calendars/events.
The final step is to start creating entries and populating your calendar with important dates related to yourself or others who are part of the same network (family members, colleagues etc). You can share these events publicly or keep them private by marking them as 'private'. Most calendar softwares also come equipped with useful tools such as reminders, tasks lists and notes which help increase personal productivity over time - all of which can be synced across multiple devices for ultimate convenience.
