What are the general rules for the duration of report submissions in the EU funded grant projects?  

General rules for submission of reports:

• Interim reports should be submitted within 60 days following end of the reporting period,
• Final reports should be submitted within 3 months after the end of the implementation period (as defined in the Article 2 of the Special Conditions of grant contracts) or 6 months if the Coordinator does not have its headquarters in the country where the project is implemented.

Note that coordinator has to inform the Contracting Authority (is EUD under the direct management modality) on any delay it may have in submitting the reports.
