people honestly believed that the various changes robbed them of days of their lives.
Granted that there was much ignorant objection.

However, the matter is not as simple as it sounds, in a commercial world. For example, suppose the terms of your home mortgage requires that you pay $1,000 on the first of each month. What happens when the calendar change is made and (say), the day after Sept. 5 is Sept. 16? Are you expected to pay the full $1000 on Oct. 1?

Such problems are the reason that England, which was in fact well-commercialized by the time it made the calendar-correction, needed extensive legislation to implement the change.
