The idea behind Day-X is simple:
many interesting moments appear when you look at time in days instead of years.

Day-X calculates these time relationships precisely and shows them on a day-by-day basis.

Most people think about age, relationships and memories in years.
However, life actually happens day by day.

When time is calculated in days instead of years,
many interesting patterns become visible.

Day-X was created to show these time relationships more precisely

Day-X allows you to schedule an automatic email
that will be sent on a specific date.

First you enter a name and a birth date
and start a calculation.

The system then shows how many days have passed since that date.

If you choose a future calculation,
Day-X determines the date on which your message should be sent.

Seven days before the scheduled delivery
you receive a reminder email
to confirm the message.

Only after confirmation will the email be sent automatically.

Day-X can also calculate the age of pets.

You can enter the birth date of your pet
and see how many days your animal has lived
or how long it has been with you.

The system can also convert pet age into
human years using common conversion factors.

This allows you to compare time between humans and animals
in a more understandable way.

Many features on Day-X are completely free to use.

can be performed without any cost.

the tokens are immediately available in your account.
