## Description

Keep your rotation and add your spouse or crewmate's with one Crew Pass — see the next day you're both home. Pay once, no subscription.

Derrick is the rotation calendar built for oilfield hands — and it actually keeps your hitch straight.

Pick your rotation once (14/14, 14/7, 7/7, 21/21, 28/28, or a custom on/off), set the day your hitch starts, and Derrick paints your ON and OFF days correctly — for years. No drift. No "off by a day." No blank calendar when the new year rolls over. That sounds basic. It's the thing every other oilfield calendar gets wrong.

NEW — your year on one page, now built for paper. The printable PDF prints on a light background: easy on toner, and your ON and OFF days stay clear in color or black and white. One year, one page — not 12 scattered months.

CREW PASS — send your rotation to your crew or your spouse as a code and a QR. They scan or paste it and import your whole schedule in one tap — no re-typing dates, no getting a day wrong. Free, works offline, no account.

FREE

Buy Pro once and keep it. No subscriptions. No ads.

Crew change shouldn't be this hard to track. Now it isn't.
