Frequently Asked Questions
How does the calculator handle month-end dates?
When calculating dates involving months, the calculator intelligently handles month-end scenarios. For example, if you're calculating one month after January 31st, the result will be February 28th (or 29th in leap years). This ensures logical and accurate results while respecting the actual number of days in each month. The calculator maintains this consistency across all calculations, whether adding or subtracting months.
What's the difference between weeks and months calculations?
Weeks are calculated as exact 7-day periods, while months vary in length (28-31 days). When you calculate using weeks, you'll get precise day-based results regardless of the month. For example, 4 weeks is always 28 days, while 1 month could be 28, 29, 30, or 31 days depending on the specific month. Choose weeks for exact day-based periods and months for calendar month-based calculations.
Can I combine different time units in one calculation?
Yes, you can combine years, months, weeks, and days in a single calculation. The calculator processes these in order from largest to smallest unit (years → months → weeks → days). This allows for precise calculations like "1 year, 3 months, 2 weeks, and 5 days" from any start date. The calculator handles all the complexity of different month lengths and leap years when combining these units.
How are leap years handled in the calculations?
The calculator automatically accounts for leap years using the standard rules: years divisible by 4 are leap years, except century years must be divisible by 400. This means the calculator correctly handles February 29th in leap years and ensures accurate long-term calculations. Whether you're calculating a few years or several decades, all leap year adjustments are automatically included in the results.
