One Calendar is a popular program for Windows that allows users to view and manage multiple calendars from various sources. The support encompasses platforms, such as Google, Live, Outlook, iCloud, Exchange, Office365, Yahoo, Nextcloud, Synology, and more.

Appointments and holidays

Adding appointments is one of the main features within this application. You can click on the desired date, assign a name and a time slot. The system ensures you will not overlook any events by allowing you to set reminders for each. The notifications are displayed in the corner of your screen.

It is worth noting that you no longer need to worry about remembering holidays or important national days. After you have chosen your country during the initial configuration, all crucial data will automatically be highlighted in green on your calendar.

In depth personalization

One Calendar is a highly customizable piece of software. Firstly, you have the option to view your dates in daily, weekly, monthly, or yearly formats. You can also modify the appearance if the default gray theme is not to your liking.

Additional features encompass the ability to drag and drop events for easy rescheduling, offline functionality, and printing support. You may also keep track of your tasks with another program called Interactive Calendar.
