Advance accrual entry

I have a query related to education domain.

Senario 1 - Due Date of Tuition fees for the month of April 2016, is 01-Jan-2016 (fees is taken in advance). What should be the date of Journal voucher where I am debiting the Student Account and crediting Tuition Fees Account? Will it be 01-Apr-2016 or 01-Jan-2016?

Senario 2 - Due date of Tuition fees for the month of April 2016, is 10-Apr-2016. What should be the date of Journal voucher where I am debiting the Student Account and crediting Tuition Fees Account? Will it be 01-Apr-2016 or 10-Apr-2016?

Please help with appropriate solution.
