Limit records

You can record as many times as you want in parallel, but you can also config the allowed limit of active records down to 1.

AM/PM format

Kimai uses localized version of the 24 hour format. But if you are used to the am/pm format, you can configure that.

Duration only

If your local laws require you to only show durations instead of start and end date-time, you can activate that mode globally.


Don’t want your users to log arbitrary timesheet records? Switch to the time-clock mode, which only allows “punch in” and “punch out” records. No more manually given start and end times.

Rate calculation

Rates can be calculated based on hourly and fixed amounts, configurable for customers, projects, activities and each timesheet record individually.

Timesheet filter

You can filter all time-records by user, customer, project, activity and date.

Weekend rates

You can configure global settings for rate factors on single weekdays, e.g. 150% for saturday and sunday.


Long term users know that old data can pile up in your dropdowns - don’t worry: you can hide them by limiting the visibility of customers, projects and activities.


Customizable permission structure. Assign different roles to your user, e.g. users can record times, teamleads can print invoices and configure project/activities, admins can configure users and customers.
