- Today was a hectic day.
- Today was a busy day.
- It’s been a hell of a day.
- I was busy at work all day.
- I was tied up all day!
- I worked all day like a lunatic.
- I was busy from start to finish.
- I barely had time to breathe today.
- I like to be busy, but today was radiculous!
- I was run off my feet today.
