From the Marketplace Datebook, here’s an extended look at what’s coming up next week:

• Why can’t Daylight Saving Time begin on a Friday at 4 p.m.? That’s when I’m ready to spring forward.

• Forty-nine years ago Neil Simon’s “The Odd Couple” bowed on Broadway. Several versions have followed for film and TV and stage. (Because you can’t get enough of a bad roommate.)

• On Tuesday, two swell guys celebrate birthdays. Barbie’s boyfriend Ken turns 53. And “Jackass” star Johnny Knoxville turns 43. (Meaning they’re both Pisces.)

• Midweek we get a look at the nation’s balance sheet. The Treasury Department issues its monthly statement for February.

• On Thursday, the Commerce Department reports on retail sales for February.          

• On Friday, the Labor Department releases its Producer Price Index.

• And with all the change in our lives it’s nice to know that there is a constant. A mathematical constant, that is. 3-14 or March 14 is Pi Day.
