I have taken all my personal days for this year.

I have used all my sick days this year.

I have five vacation days left this year.

Now a days, people rely heavily on technology for communication.

The judgement days are approaching.

In the days of yore, knights roamed the land in search of adventure.

I love shopping on boxing days.

Solar days are the time it takes for the Earth to complete one rotation on its axis.

I love taking days off to relax and recharge.

Many people celebrate saints' days by attending church services and participating in religious rituals.
