Fiscal Year Beginning and Ending Dates on 1040 and 1041 Tax Returns

My father died on 09/14/2024 and he had a Trust. Should the fiscal Beginning and Ending dates on his Final 1040 be 01/01/2024 and 09/14/2024 respectively and the fiscal Beginning and Ending dates on his Initial Trust 1041 be 09/15/2024 and 12/31/2024 respectively or will the entire 2024 tax year be more appropriate for both?
