Orthodox Jewish communities in the United States are raising concerns about proposed legislation to make daylight saving time permanent, citing potential disruptions to religious practices that rely on precise timing linked to sunrise. The Sunshine Protection Act of 2025, introduced by Representative Vern Buchanan (R-Florida), passed the House of Representatives with a 308-117 vote and awaits Senate consideration. The bill would eliminate the biannual clock changes by keeping daylight saving time year-round, a shift supported by President Donald Trump, who has described seasonal clock adjustments as unnecessary.

For observant Jews, daily prayers are scheduled according to natural light rather than conventional clock time, with the first morning prayer traditionally recited close to sunrise. Rabbi A.D. Motzen, national director of government affairs for Agudath Israel of America, an organization representing Orthodox Jews, emphasized that later sunrises under permanent daylight saving time could delay prayer times significantly. Rabbi Josh Joseph, executive vice president of the Orthodox Union, also noted that such delays could complicate early morning routines, particularly in regions like the Midwest and Mountain states where sunrises could be pushed beyond 8 a.m. during winter months.

Agudath Israel has submitted a letter to Congress warning that the proposed change could "throw into disarray" the scheduling of morning prayers and related rituals, potentially discouraging synagogue attendance and interfering with work or school schedules. Their analysis indicates substantial geographic variation in impact: cities like South Bend, Indiana, could experience sunrises after 8 a.m. on roughly 150 days annually, with 55 days seeing sunrises after 9 a.m. Comparable concerns apply to Helena, Montana; Boise, Idaho; and Bismarck, North Dakota, where delayed sunrises are predicted for several weeks in winter.

Rabbi Yosef Chaim Danziger of South Bend’s Hebrew Orthodox Congregation echoed these concerns, highlighting the potential conflict between late sunrises and the start of the typical work and schoolday, which may impose undue burdens on community members. The requirement for communal morning prayers, often necessitating a quorum of ten men and timed near sunrise, may become increasingly difficult to meet. Motzen suggested that some individuals might forgo synagogue attendance or pray individually at workplaces, potentially affecting communal religious life.

Daylight saving time currently runs from March to November in most U.S. states, with exceptions including Arizona, Hawaii, and several territories. Permanent daylight saving time would mean darker mornings in winter and extended evening daylight. While proponents point to benefits such as avoiding clock changes and increased evening daylight for recreational activities, critics—including parents, health professionals, and sleep researchers—warn of safety concerns for children and disruptions to circadian rhythms.

Orthodox Jewish families, which tend to have larger households than other Jewish groups, share worries about children’s safety during dark morning hours. Similar timing issues affect Muslim communities, whose morning prayers must conclude at dawn, suggesting broader religious implications beyond Jewish groups.

The U.S. Senate’s consideration of the Sunshine Protection Act is pending ahead of a scheduled recess on August 7. Advocates opposing the bill urge lawmakers to consider the year-round impact on religious observances and community routines, particularly in northern and midwestern states where late winter sunrises could be most disruptive.
