Daylight Saving Time is controversial due to its alleged negative impact on individual well-being. Using panel data from Germany we find evidence that the transition to summer time has negative influence on general life satisfaction and mood, which is stronger for those in full time employment.

The otherwise seemingly robust age U-shape effect on life satisfaction in pooled OLS regressions is refuted with the German SOEP when controlling for panel fixed effects and respondent experience in the panel. Interviewer characteristics also impact significantly on life satisfaction responses.
