"These days" in English, when it means the immediate past including the present, is usually translated as ces jours-ci.

I don't sleep well these days. -- Je ne dors pas bien ces jours-ci.

Ces temps-ci doesn't work in French.

Hi Rita,

This point must surely depend on context?

Is it required to express or make reference to

 1. periods non-defined?

 or

 2. periods between sunrise and sunset?

Bonne journée
