Weeks = Days / 7
Example: Employment Tenure
Start Date: January 1, 2020, End Date: January 1, 2023 (or today if current)
Days: 1,095 days (3 years)
Years: 1,095 / 365.25 = 3.0 years

Frequently Asked Questions
How do I calculate tenure for current employees?
Enter the start date and leave the end date blank. The calculator will automatically use today's date to calculate current tenure. This gives you the length of service from start date to today.
Does the calculator account for leap years?
Yes, the calculator uses 365.25 days per year to account for leap years. This provides more accurate year calculations over longer periods. For precise calculations, it uses the actual number of days between dates.
How do I calculate tenure if there was a break in service?
Calculate tenure separately for each period of employment, then sum them. For example, if worked 2000-2005 and 2010-2020, calculate each period separately. Some organizations use continuous service (ignoring breaks), while others use total service (sum of periods).
What if I need tenure in months only?
The calculator shows tenure in multiple formats including months. Use the months value displayed. For example, if tenure is 2.5 years, it's also shown as 30.5 months. You can use whichever format you need.
How do I calculate tenure for multiple employees?
Calculate each employee separately. For average tenure, calculate each employee's tenure, then average them. For example, Employee A: 5 years, Employee B: 3 years, Employee C: 7 years, Average = (5+3+7)/3 = 5 years.
Does tenure include probation periods?
Typically, tenure includes the entire employment period from start date, including probation. However, some organizations may exclude probation from tenure calculations for certain purposes (like benefits). Check your organization's policy for how probation periods are handled.
