## How to calculate the countdown from a date to another

To calculate the **number of days in the countdown between dates**, follow these few steps:

- Count the number of days in the first month by
**subtracting the number of days in the month and the day number after the starting date**(we don't count the first partial day in this date countdown). - Find the
**number of days in the final month**: simply add the day number of the final date. - Check if there are whole years (i.e., if you can identify pair of the same months between the two dates), and add
**365 days**(**366**if the months include a leap February) for each of them. - Add the
**number of days in the full months between the two dates**. Remember to use the correct number of days for each month! - Sum all the contributions to find the number of days in the countdown between the dates.

## Refining the countdown between dates: adding the time

If the number of days is insufficient for you, you can quickly improve it by adding time. To find your countdown of time and date, remove **one day** from the result of the section above and proceed according to the following steps:

- Find the
**number of hours on the first day**by subtracting the initial time from midnight. Be wary of borrowing the correct values if necessary! - Sum the result of the passage above to the
**number of hours, minutes, and seconds on the final date**. - If the result is higher than
**24 hours**, remove 24 hours, and**add a day to the countdown**.

That's it!

## Example of countdown and timer to date

Let's try to calculate a countdown and timer to a date, say the first of May, from the previous year's 17^{th} July.

- Find the number of days in the initial month (July): subtract
**31**and**18**: $31-18=13$. - Consider only a day in May.
- Count the number of days in the entire months between July and May: there are
**273**days if the year is not leap. - Sum all these numbers: $273+13+1 = 287$. This is the value of the countdown.

If we fix the starting time to 14:30 and the final time to 09:45, we can also give you an example of calculating the time countdown.

- Find the number of hours on the first day: subtract
**24:00**and**14:30**. The result is $24:00-14:30 = 09:30$. - Sum this number to the time of the final date: $09:30+09:45 = 19:15$.
- Subtract one day from the day countdown to account for the incomplete final day: the final result is
**286 days, 19 hours, and 15 minutes**. Start counting!

### How long is the countdown between the dates of the equinoxes?

Assuming the dates of the equinoxes to be the **20 ^{th} March** and the

**20**, the

^{th}September**countdown between them would last 183 days**. To find this result:

- Find the number of days in March: subtract the day after the equinox (the
**21**) from^{st}**31**(the duration of the month) to find**31 - 21 = 10**. - Sum the number of days in September:
**10 + 20 = 30**. - Count the number of days in the months between the two: there are
**153**days.

The result is **153 + 30 = 183 days**
