No - you cannot change the nominated end date for a fixed personal cause.
You need to set the specific funding goal for your project and the time limit to meet this goal prior to starting your campaign.
This can't be changed once pledges start being made.
The time frame for projects is between 1-60 days (we usually recommend 30-50 days). The project deadline is the last date by which supporters can contribute funds towards your target.
Unless a project has been adjusted for technical reasons, all projects end at 12 noon on the final day.
It is important that you market your campaign and seek pledges within your time frame. You will receive regular notifications regarding your campaign's progress.
