Those 1,834 days include roughly 262 full weeks and about 5 complete years. The difference between the rounded figure and the exact one matters here: dividing 1,834 by an average year length gives 5.02 years, while walking real calendar months gives 5 years, 0 months and 8 days. Both answer slightly different questions, so both are shown above.
