District councillors approved the short-term measure - proposed by Ashbourne Town Team - at an extraordinary council meeting on 27 July.
The initiative replicates free parking after 2pm throughout the month of December, which the Council has enabled for the past 13 years to help boost trade at a vital time of year for local traders.
A resident parking permit issued to all Derbyshire Dales households every year also makes parking free every day of the year before 11am and after 4pm.
The estimated £45,000 cost of encouraging shoppers to return to town centres by suspending charges after 2pm in September will be met from the District Council's Covid Funding Reserve.

A report to the meeting stated:
"Irrespective of the level of car parking charges, the national restructuring of the retail sector, influenced by the rise in online sales, means every town faces the challenges of declining high street spend and footfall.
"Reducing car parking charges is not therefore considered to be the panacea for all of the challenges facing our town centres. It is also not a financially viable option for the District Council given the critical importance of car parking income to sustaining our overall financial position, which is already under strain."The report estimated the cost of making parking completely free throughout September in the car parks in Ashbourne, Bakewell, Matlock, Matlock Bath and Wirksworth at more than £200,000.
