Flu-shot uptake at a workplace clinic when the reminder mailer asked employees to write the date and time they planned to go (regression-adjusted; 37.1% vs 33.1% raw). 3,272 employees at one firm, fall 2009 (Milkman et al.).

Overview
Help people turn an intended action into a concrete plan: ask for a date and time, then offer a reminder. Date-and-time prompts increased follow-through in a workplace flu-shot trial; meaningful start dates also helped savings take-up.
Many people who intend to act don't; forgetfulness, procrastination and the lack of a concrete plan all contribute to the gap between intentions and actions (Milkman, Beshears, Choi, Laibson and Madrian).
Fits when
- One-time actions available for a short window, like a clinic on a single day
- Asking for both a date and a time, not a date alone
- Delayed starts labelled by a date that feels like a new beginning: a birthday, New Year's, the first day of spring

Good to knowFit and evidence notes
- Fit to consider
- For recurring gym schedules, do not assume a planning prompt improves attendance: one 13-day trial found no gain over recalling past visits.
- About the evidence
- The strongest benefit evidence concerns one-time actions. In one 13-day trial at a single gym, asking members to choose visit days and hours did not increase attendance.
