If current time is 15:29, for example, the above "Get Items in Range `1` to `Time Between Dates`" will result in 8 hourly weather data at 15:00, 16:00, …, 22:00, respectively. However, we want to also get the weather data at 23:00. That’s why we need to add 1 to the `Time Between Dates` variable to achieve this goal.
