la semaine des quatre jeudis
On Rare Occasion
(the week of the four Thursdays) •
Used to express that something will never happen.
In the past, Thursday was a break day for pupils and teachers. So, having a week with four Thursdays would have been a wonderful dream, but it will never happen.
" - Quand vas-tu me présenter à tes parents?
- La semaine des quatre jeudis."
" - When will you introduce me to your parents?
- On the week of the four Thursdays."
