Choose a Different Completion Date When Completing a Task

When you complete a task late, Nekst lets you pick the date it was actually finished instead of defaulting to today. This keeps any dependent tasks scheduled off that task from cascading forward from the wrong date.

Complete a task with a chosen date

1. Open the task you want to complete
2. In the top left of the task drawer, click the calendar dropdown next to the Mark Complete pill
3. Pick the date the task was actually finished. You can only pick from today or a day in the past. You can NOT set a task as completed in the future.
4. The task is marked complete with that date

If you just want to complete the task with today's date, click Mark Complete directly — skip the calendar.

If the task has Dependent Tasks

When you complete a task with a back-dated date and that task has Dependent Tasks scheduled off it, Nekst opens a Reschedule Dependent Tasks? dialog so you can choose which date the dependents should be rescheduled from:

• Use selected completion date — dependent tasks recalculate from the date you just picked (the recommended choice when back-dating to fix a late completion)
• Use today — dependent tasks recalculate from today

Pick the option that reflects what really happened, then click Confirm.

Edit the completion date of an already-completed task

1. Open the completed task
2. Find the green Completed {date} pill in the top left of the task drawer
3. Click the pencil icon inside the pill
4. Pick the new completion date

You'll see a confirmation that the completion date was updated, and the task row in your task list will reflect the new date immediately. However, the Dependent Tasks will not adjust for a second time. You will need to manually update the deadlines for any dependent tasks.

How history records completions and date changes

When you mark a task complete — whether you use today's date or pick an earlier one — history records the actual moment you completed it (date and time), not the date you selected. The selected date is what Dependent Tasks calculate from; the history entry timestamps when the action happened.

If you later edit the completion date of an already-completed task, that's a separate event. Nekst logs a "Completion date changed" entry showing who made the change, the previous date, and the new date.

• Project history: open a transaction and click History
• Task history: open a task and view the comments/events list
• Filter: use the event filter to show or hide "Completion date changed" entries

Notes

• Future dates are not allowed. You can pick today or any past date.
• Only fully-completed tasks can have their completion date edited after the fact.
• The date picker is available on the web app. On the mobile app, tasks complete with today's date as before.
