Frequently Asked Questions
How are months calculated in date math?
Month calculations are more complex than they might appear at first glance. They take into account the varying lengths of different months (28-31 days) and handle special cases automatically.
The day of the month is preserved whenever possible, but when calculating 1 month ago, if the target month is shorter than the current one, the calculation adjusts to use the last day of that month. For example, if today is March 31st, one month ago would be February 28th (or 29th in leap years).
How many days are in 1 month?
In 1 month there are approximately 30 days. However, this number can vary by several days depending on the specific months involved. For instance, if your period includes February, you'll have fewer total days than if it includes months with 31 days. Leap years add another layer of complexity, potentially adding an extra day to February.
Key factors affecting the total:
- Which specific months are included in your period
- Whether any leap years fall within the timeframe
