Calculating date 45 days from now.

[Dave Walley]

Hi.

I need a create a script to calculate the date 45 days from now. Can anyone point me in the right direction. Is there a function to do this?

Any help greatly appreciated.

Thanking you.

There is a set of GNU utilities that you can pick up from the HP-UX porting and archive center. One of the utilities is a new 'date' command that will allow you to figure dates like you want. I currently use it and it works pretty well.

Here is the link to the package:

This came up yesterday. The solution is in this thread:

There is a very simple way to do this and it was used on projects of HP and a big e-commerce house (in other words.. it works, it's simple and does not bloat the code).

Step1. Get the number or seconds from epoch. Date and other functions (what language are you using?) then add 3888000 to that, and convert back into 'human' form.

The number 3888000 is the number of seconds in a day (86400) times the number of days (45). No screwing around with calendars or anything like that. Works every time.

Party on, Garth.

Dave,
I have an awk script I created just for this purpose, attached. The way I use it in a script is as follows:
echo 'mm/dd/yy/nn' | awk -f date_conv.awk
where nn is number of days to add (or -nn, subtract).
The output comes back as mm/dd/y.
Hope this helps,
Mo
