Brighton and Hove City Council could become the first in the country to change school term times to make it more affordable for families to go on holiday.
The idea is that by reducing the summer holidays an extra week could be offered in the autumn.
The number of fines given to parents for taking their children out of school during term term has rocketed in recent years - but many parents think it's a price worth paying.
Over the last three years, the number of families fined in Brighton for unauthorised absence has risen from 127 in 2012 / 13 to 434 a year later and last year it was 983.
The rise is thought to be in part because schools are being stricter in how they impose Government rules.
Many parents say they would welcome a change. Calls to group inset days into one week are also in consultation.
A new week's holiday would have to sit around exam timetables leaving only a select number of dates available.
Plans will be discussed by the council next week with any changes not expected to be implemented until September 2017.
