The 'hours left' (HL) value is designed to allow a user to specify how many hours he plans to use to complete a task, as a way to link the progress value expressed in percentage with working hours.

By default, when an activity is being added the Hours left field on the Activity details screen is automatically filled with the same number of hours as in the Estimated hours for this activity field.

Estimated hours are synced with hours left only as long as the activity is not started yet, i.e. no time entries are entered. After the activity is started, changing estimated hours will not affect hours left.

You can change the HL value at any time.

You can also manually adjust the calculated number of hours left for an activity when making a time entry in Time Logs.

To adjust hours left for a task in Time Logs:

1. Go to Time Logs.
2. Indicate the hours left in the appropriate field (next to Progress).

To adjust HL and activity progress (completion rate) of an activity:

1. Click the activity' name link to open Activity Details screen.
2. Indicate the hours left in the appropriate field (next to Progress).

You can adjust personal hours left using the Assignees dialog box in Activity Center or on Activity details screen. To do so:

1. In Activity Center, click the Assignees button. Alternatively, click the edit (pencil) button ().
2. Click the clockface button ().

When an assignee is removed from the team, both their estimated hours and hours left are deducted from total EH and HL.
