Um, how about My Bike Commute?

15 to 16 miles each way, depending on route.

Usually good. Mostly but not always clean pavement. At least 50% has a wide shoulder. The morning run uses about 2 miles of bikeway.

Moderate.

Mostly suburban.

Yes. Not long but one is steep, max grade ~10%. Total elevation gain each way is 1500 to 1700ft.

Technically speaking, once per day.
Since this really asks "how often", then every day if no other commitment or weather intervenes. I rode this April through mid-December when events got in the way, and I've ridden this only once this January.

7:15 to 7:30AM, typically.

All of them (except the tandem). The UO8 gets the bulk of the later-fall and winter use because it is equipped with generator lights. (I also use a powerful battery light and rear blinky.) Some have tires less suited to the debris level. The Bianchi wears Gatorskins and is especially nice. They are all good.

I could go with Nao, Gina, Francis, Mario, but that would be silly. They don't have names other than Peugeot, Motobecane, Raleigh, Masi, Centurion, Bianchi, Bertin.

Lunch.

Yes.

Woburn, MA in the morning. Waltham, MA in the evening.

For the bike? In my office.

No.

They have electricity, plumbing, heat, a small cafeteria with no food service.

From home? I already answered that. From the office? 4:50 to 5:10 PM typically.

I drive if necessary. I could take a commuter train for part of the trip but it wouldn't save much distance or time so I have not done so yet.
