hello everyone,

How do I just print the day.

What I want to do is, today, for example 14.12.2022, how can I get the day "13" for yesterday.

In short, how can I just print the previous day?

If you are using scripting and not an expression, then

```python
yesterday = system.date.addDays(system.date.now(),-1)
# for just the day of month add this
dayOfMonth = system.date.getDayOfMonth(yesterday)

```

Thanks, can I use this in reporting schedule parameters?

How can I do it in the report?

Yes you can do this in a report, but for a parameter it is easier to use an expression.

```auto
getDayOfMonth(addDays(now(0), -1))

```

In the report parameters area, these buttons can show you available functions, logic operators, and browse for tag paths
