## What is the method used to calculate how many days there are between two dates?

If you wish to learn more about how to calculate the days between two dates by hand, follow these steps. For example, if you were born on September 5th, 1970, and you want to work out **how old you are in days** as of June 5th, 2022.

**Subtract the start year from the end year.**Since September 2022 has not yet arrived, we know the last complete year is September 2021, so we subtract:`2021 âˆ’ 1970 = 51`

.**Convert the result to days:**Each year is`365.25`

days (we include the`.25`

to cater for leap years). The number of days in`51`

years would be`365.25 Ã— 51 = 18,627`

days.

**Find the number of months from September 2021 to June 2022.**`Month 12 âˆ’ Month 9 = 3`

months in 2021.`Month 6 âˆ’ Month 1 + 1 = 6`

.- So the number of months is
`9`

. **Multiply the average number of days in a month by our 9 months:**`365.25/12 Ã— 9 = 273.94 days`

.

**Add the total number of days together and round the final answer:**`18,627 + 273.94 = 18,902`

. Note that this includes the end date â€” if it didn't, it would be`18,901`

days.

- If this crosses several years, you should
**calculate the number of full years**. - For the period left over, work out
**the number of months**. - For the leftover period, work out
**the number of days**. - Convert these values to
**one unit over all periods**(whether it's seconds, minutes, days, etc.). - Finally,
**add all the values together.**

### How many days are there between the 4th and the 26th of July?

There are **22 days** between the 4th and the 26th of July.
