# Best Calendar Software - Page 6 *By [Neeraja Prakash](https://research.g2.com/insights/author/neeraja-prakash)* Calendar software is intended to organize a user’s tasks, meetings, and goals in a visually simplistic way, which helps streamline the internal activities of an entire business. Calendar software facilitates the creation of electronic agendas that can be accessed, edited, and shared with employees company-wide. This software can also be used to schedule tasks for teams, share community-wide events, as well as notify team members about their peers’ paid time off, birthdays, etc. Calendar software can be sold as a standalone product but is often included as part of a larger office suite. If it is part of a larger suite, calendar software is an integration that works with other standard office products such as [email](https://www.g2.com/categories/email), [digital business card](https://www.g2.com/categories/digital-business-card), and [video conferencing](https://www.g2.com/categories/video-conferencing) tools. Calendar software differs from [Online appointment scheduling software](https://www.g2.com/categories/online-appointment-scheduling). The [best calendar software](https://learn.g2.com/best-calendar-app) is focused primarily on organizing meetings, tasks, and events in a visual format that can be shared team-wide. On the other hand, online appointment scheduling tools focus on scheduling appointments for external users, taking payments for appointments, and communicating with clients. Buyers may consider solutions that provide both calendar and online appointment scheduling functionalities in the same product, but they ultimately have different use cases.

Ease of collaboration is a common benefit that is integral for events and tasks involving large groups. Other customization options include ongoing calendar event scheduling and adjustable event notifications. ### Why Use Calendar Software? Since operating efficiently relies heavily on organization and productive collaboration, businesses will primarily benefit from a calendar’s scheduling feature. It’s common for plans to change, considerably more often within a large team. With calendar software, miniscule appointment changes can be adjusted very simply. Many calendars offer alerting functionality, so guests are notified when appointments change. In addition, the availability and capacity sharing features within calendar software facilitate transparency and allow team members to work around everyone’s personal schedule.

Free options allow businesses to choose a calendar software that fits perfectly with their team without the risk of immediate cost.

A calendar is more approachable than a normal to-do list, but also gives a sense of a deadline. ### Kinds of Calendar Software Calendar software will typically appeal to either a casual user or business user depending on its key capabilities and interface. While both users are looking for basic scheduling, a casual user will gravitate toward free, aesthetically pleasing, and easy-to-use software that works well on a mobile device. A business user will get more use out of calendar software that facilitates easy collaboration and includes customization options. **Suite Calendars –** Collaborative teams benefit greatly from calendars that are a part of a larger suite of applications.

The interface is typically straightforward and will not have many added features or enhancements beyond its basic format. Standalone calendars are clean and ideal for those who don’t have numerous appointments or tasks to keep track of. **Client Scheduling Calendars –** Calendar software used specifically for client bookings ensures organized appointment scheduling and will oftentimes allow clients to take the reins and schedule their own appointments.

If employees choose to stray from the company’s choice of calendar software, sharing calendar data between multiple calendar applications can prove to be a challenge. Many calendars do not allow sharing with competitor applications. To prevent any mishaps, ensure the entire company sticks to one platform. **Appointment Time Restrictions –** Calendars will typically only offer 15–30-minute time spans for invitations, making it difficult to plan meetings that are fewer than 15 minutes long.
