## 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:

1. 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).
2. Find the number of days in the final month: simply add the day number of the final date.
3. 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.
4. Add the number of days in the full months between the two dates. Remember to use the correct number of days for each month!
5. 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:

1. 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!
2. Sum the result of the passage above to the number of hours, minutes, and seconds on the final date.
3. 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 17th July.

1. Find the number of days in the initial month (July): subtract 31 and 18: $31-18=13$.
2. Consider only a day in May.
3. Count the number of days in the entire months between July and May: there are 273 days if the year is not leap.
4. 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.

1. Find the number of hours on the first day: subtract 24:00 and 14:30. The result is $24:00-14:30 = 09:30$.
2. Sum this number to the time of the final date: $09:30+09:45 = 19:15$.
3. 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 do you calculate the countdown from a date to any other day?

To calculate the number of days between any dates for a countdown, follow these easy steps:

1. Find the number of days in the starting month by subtracting the day number after the initial date from the number of days in the month.
2. Sum the result to the number of days in the final month.
3. Count the days in the full months between the two dates. If there are full years, add 365 or 366 days, and sum the results.

That's it: start the countdown!

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

Assuming the dates of the equinoxes to be the 20th March and the 20th September, the countdown between them would last 183 days. To find this result:

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

The result is 153 + 30 = 183 days
