What Is Calendarization?

Calendarization is the process of accurately allocating utility bill usage and cost data for reporting purposes. It does this by dividing the data into day-size chunks and allocating each chunk to the appropriate calendar month.

Why is this necessary? Well, most utility bills have start and end dates that do not correspond with the first and last date of each month.

Without calendarization, analyzing or reporting on the month of October’s energy usage is difficult, because half of the month’s usage may be on October’s bill while the other half is on November’s.

Calendarization will take this bill and prorate it into the appropriate months. The 17 days on the bill that represent October’s usage will be allocated to October, and the remaining days will be allocated to November.

Thus, we can see that calendarization adjusts data to be more representative of actual monthly energy usage, allowing for more accurate month-to-month analysis and comparison.
