day-to-day

1. Daily; regularly occurring. And you will oversee the company's day-to-day operations while I'm traveling. The superstar comedian's latest non-fiction book provides a quirky insight into her day-to-day life, and reminds you that she's just like us regular folk. It may not be the flashiest model of hatchback, but it's perfect for the day-to-day needs of a young family.

2. Current. Typically said of one who has little concern for the future. You need to stop focusing only on your day-to-day activities and think about where you want to go to school next year. In our receptionist's absence, no one is up on the day-to-day goings-on in the department. Like, what is this gigantic box is doing here? How are you ever going to save money if you only worry about day-to-pleasures and instant gratification?

3. Subject to daily evaluation, as of an injured athlete. I hear that their first baseman is day-to-day with a pulled hamstring. Nah, that's all I'm cleared to do in practice. They still consider me day-to-day. Roberts has filled in admirably while the team's everyday goalie has been day-to-day with back spasms.

day to day

Also, from day to day.

1. Continuously, without interruption, on a daily basis. For example, Running this office day to day is not an easy task. [Late 1800s]

2. live from day to day. Be interested only in immediate concerns, without thought for the future. For example, Jean lives from day to day, planning nothing in advance. Also see live for the moment.
