Calculation on Dates

Hi everyone,
can we run calculation on dates? I’m converting to Julian Day to be able to do some basic math on 2 dates but i was wondering if there’s a better way to do it?

Thanks for any help

what kind of calculation on dates ?

Pretty much what you are showing me lol
Date A - Date B

I’m tempted to start… laughing ahahahah
Thanks a lot

Even easier: Look into the nodes in the Input section of your library, under “DateTime” and “TimeSpan” as there is a TimeSpan.ByDateDifference there.

Specifically this may be of interest:

Can’t believe i missed this… thanks for the heads up

that makes two of us

It’s easy to overlook stuff - I do it at least once a week and then go ‘oh yeah that node… well next time.’ :slight_smile:

i know this is an old post, but you have worked with times.

I found the timespan nodes…

but what i want is to calculate with dates so i have today 7-6-2022 and i want to add or subtrackted 2 days…

i want to read a file with a date entry then see what date it is now… and then get a list of all the working days (so no weekends)

for example the file read is from 1-6-2022… today is 7-6-2022
i want a list
2-6-2022
3-6-2022
6-6-2022

is fine if the weekends are in for now… i will filter that out with the weekdays node

Here is a quik way to get the total of days

that is not what i mean…
the input is 1-6 and the date today 7-6…

the output needs to be
2-6-2022
3-6-2022
4-6-2022
5-6-2022
6-6-2022
7-6-2022

The date format is based on your computer settings.
If you need to return it as a string then you can extract each component and reassemble them in the order you want

Without python to get the total without work days

Date Time.dyn (35.5 KB)

but time span gives the number of days between two dates…

i need the dates it self

the input is 1-6 and the date today 7-6…

the output needs to be
2-6-2022
3-6-2022
4-6-2022
5-6-2022
6-6-2022
7-6-2022

You also have that but your initial question was :
“but what i want is to calculate with dates so i have today 7-6-2022 and i want to add or subtrackted 2 days…”

sorry my question wasn’t clear…

No worries :slight_smile:
You have the date here if you add this node:

thanks got it
