OnTime Group Calendar is group scheduling software for organizations working with Microsoft 365, Microsoft Exchange, or HCL Domino. It brings team calendar views, availability polling, meeting assistance, calendar sharing, external scheduling links, time-off approval workflows, and meeting-room or resource scheduling into one system. It is aimed at teams that coordinate people, rooms, resources, and shared availability rather than individuals seeking a simple personal calendar.

The published plans show a freemium structure. OnTime Freemium provides core group calendar features for up to 50 users in HCL Verse/Notes and Domino environments. The product also has a 60-day free trial. Premium licensing is customized by organization size and the number of users or resources. The Premium plan includes customized licensing, with storage and sync tasks available in the Small Business solution, plus maintenance and support options. Purchases are invoiced and paid by bank transfer, so organizations should expect a sales-led pricing process rather than a standard public rate.

Its strongest fit is an environment already centered on Microsoft or HCL systems. Integrations include Microsoft 365, Microsoft Exchange, HCL Domino, Microsoft Teams, and HCL Connections, while the platform options include web, API, and self-hosted deployments. Calendar synchronization is two-way, online meetings can be integrated when creating events, and an Open HTTP API add-on supports further connectivity. Teams that need approval-based time-off planning, scheduling on behalf of others, reporting exports, and resource calendars get a broad coordination toolkit. Organizations outside the Microsoft and HCL ecosystem, or those wanting a narrowly focused personal calendar with simple consumer pricing, should consider a different type of calendar product.
