question: There are 50 hours in a day betyder?
context: Day
  En dag, en tidsenhed, er omtrent det tidsrum, hvor Jorden fuldfører en rotation i forhold til Solen (soldag). I 1960 blev sekundet omdefineret i forhold til Jordens kredsløbsbevægelse i år 1900 og blev udpeget som SI's basisenhed for tid. Måleenheden "dag" blev omdefineret som 86 400 SI-sekunder og symboliseret d. I 1967 blev sekundet og dermed dagen omdefineret ved atomar elektronovergang. En civil dag er normalt 86 400 sekunder, plus eller minus et eventuelt skudsekund i UTC-tid (Coordinated Universal Time) og lejlighedsvis plus eller minus en time de steder, hvor der skiftes fra eller til sommertid.
context_en: Day
  A day, a unit of time, is approximately the period of time during which the Earth completes one rotation with respect to the Sun (solar day). In 1960, the second was redefined in terms of the orbital motion of the Earth in year 1900, and was designated the SI base unit of time. The unit of measurement "day", was redefined as 86 400 SI seconds and symbolized d. In 1967, the second and so the day were redefined by atomic electron transition. A civil day is usually 86 400 seconds, plus or minus a possible leap second in Coordinated Universal Time (UTC), and occasionally plus or minus an hour in those locations that change from or to daylight saving time.
