The Linux date command displays the current date and time of the system. While writing the shell scripts, I realise that sometimes we are required to find future dates—for example, dates after 10 days, 2 months, or 1 year, etc.

The date command provides an option to display the future dates as described.

-d, --date=STRING          display time described by STRING, not 'now'

Let’s understand this with some examples:

Display current date: Simply type 「date」 to display the current date and time of system.
```
date     

Thu Sep 22 03:58:36 UTC 2022
```
Date after 10 days: What will be the date after 10 days? The below command will show you the desired results:
```
date -d "+10 days"

Sun Oct  2 03:58:48 UTC 2022
```
Date after 3 months: Similarly to find the date after 3 months, type:
```
date -d "+3 months "

Thu Dec 22 03:58:58 UTC 2022
```
Date after 1 year: What will be the date just after 1 year?
```
date -d "+1 year"

Fri Sep 22 03:59:05 UTC 2023
```

These commands are helpful to find the day, month date in the future after a specific duration. We can also format the date on display. Here are a few more examples to view future dates and times.
