You can specify your working hours and days to match when your team is actually working. This can then be applies to the timing metrics so that the time outside the working hours is excluded from the metrics.
You can find these settings in Account Settings, located under the main menu:
In Account Settings ->Account tab, you can set hours and select days. These are your account-level settings that will be applied to all charts within a Screenful account.
When you create a chart using the Time in state unit, there is a checkbox Only working hours. When selected, the chart will calculate the timing metrics from the working hours only:
In the Timing Insights, weekends and evening time are included in the calculations by default. To change that, click the Settings button on the top right:
In the settings modal, change Tracked time to Use working hours only.
Now all the timing metrics shown under the Insights âž” Timings tab include only the time spent during the office hours.
You can also choose to only include working days on the Burndown chart by checking Exclude non-working days in the chart editor.
When checked, the ideal burndown is flat during the non-working time (e.g. weekends).
