The COVID-19 pandemic and associated lockdowns triggered worldwide changes in the daily routines of human experience. The Blursday database provides repeated measures of subjective time and related processes from participants in nine countries tested on 14 questionnaires and 15 behavioural tasks during the COVID-19 pandemic. A total of 2,840 participants completed at least one task, and 439 participants completed all tasks in the first session. The database and all data collection tools are accessible to researchers for studying the effects of social isolation on temporal information processing, time perspective, decision-making, sleep, metacognition, attention, memory, self-perception and mindfulness. Blursday includes quantitative statistics such as sleep patterns, personality traits, psychological well-being and lockdown indices. The database provides quantitative insights on the effects of lockdown (stringency and mobility) and subjective confinement on time perception (duration, passage of time and temporal distances). Perceived isolation affects time perception, and we report an inter-individual central tendency effect in retrospective duration estimation.

COVID-19 大流行和相关的封锁引发了全球范围内人类日常生活的变化。在 COVID-19 大流行期间，Blursday 数据库提供了来自 9 个国家的参与者的主观时间和相关过程的重复测量值，这些参与者在 14 份问卷和 15 项行为任务上进行了测试。共有 2,840 名参与者至少完成了一项任务，439 名参与者在第一阶段完成了所有任务。研究人员可以访问数据库和所有数据收集工具，以研究社会隔离对时间信息处理、时间透视、决策、睡眠、元认知、注意力、记忆、自我感知和正念的影响。Blursday 包括定量统计数据，例如睡眠模式、性格特征、心理健康和锁定指数。该数据库提供了关于锁定（严格性和流动性）和主观限制对时间感知（持续时间、时间流逝和时间距离）的影响的定量见解。感知孤立影响时间感知，我们报告了回顾性持续时间估计中的个体间集中趋势效应。
