How do you get the current day of the month and write it to a tag in a gateway script?  
This is what I have so far

```auto
now = system.date.now()
dayOfMonth = system.date.getDayOfMonth(now)
system.tag.write("[default]CurrentDay")

```

This is setup to put out an integer. If your tag type is string remove the int()

```auto
today = system.date.now()
dayOfMonth = int(system.date.format(today, "dd"))
system.tag.write("[default]CurrentDay",dayOfMonth)

```

the value for the tag is still null.

</div>

what are you putting this script in?

```auto
today = system.date.now()
dayOfMonth = int(system.date.format(today, "dd"))
print dayOfMonth

```

If you put this in the script console it should print the number

this seems to be using system, make sure you have `import system` before the code maybe? I’m not a jython expert, you can also `import datetime`

this worked

```auto
dayOfMonth = system.date.getDayOfMonth(system.date.now())
system.tag.write("[default]CurrentDay",dayOfMonth)

```

If this is on a timer script, it seems like a bit of running around the mulberry bush to get what could be done as an expression tag.

```auto
dateFormat(now(),'d')

```
