Reference Definitions Used
These definitions are used across TimeDate.org to keep results consistent.
Definitions
- 1 minute = 60 seconds
- 1 week = 7 days
- 1 month = 4 weeks + 2 days (30 days)
- 1 year = 12 months
- 1 year = 365 days
- 1 year = 52 weeks
Understanding decimals (remainder style)
If a result has decimals, you can interpret the fractional part using smaller units. Example: if the target unit is months, TimeDate.org treats 1 month = 30 days = 4 weeks + 2 days. That allows remainder forms like “weeks + days”.
Frequently Asked Questions
Short answers to common questions about this conversion.
How do I convert months to years?
Use result = value × factor. We display the factor and the full math operation above.
Why do some pages show decimals?
Because the value does not divide evenly into the target unit. When that happens, we also show a readable remainder-style interpretation using smaller units.
What does “1 month = 4 weeks + 2 days” mean?
TimeDate.org defines 1 month as 30 days. Since 4 weeks = 28 days, the remainder is 2 days: 30 days = 4 weeks + 2 days.
Are these definitions universal?
These are TimeDate.org reference definitions designed for consistency across all conversion pages. They may differ from calendar-month variability (28–31 days).
