You can edit the date notes where created or that tasks where completed. This means if you are too busy to record some work at the time it is done you can add it later and amend the date so your farm history is accurate. You can also add historic farm records to your farm history. 

Tap on the note or task you want to alter. Select edit next to the date you wish to change and then tap ‘Done’.

Open your task from the activity list, click on ‘Edit’ at the top of the task panel, from here you can change the dates.
