How do I count events for the past 45 days when the start date is the 15th of each month?

Please Help !!!!

I am trying to create an SPL query to count events for the past 45 days from the start date the 15th of each month, so for instance, January 15 through the past 45 days.

index=okta  earliest=-45d@d latest="1/15/2019:24:00:00" 
| stats min(_time) as lt max(_time) as ft dc(targets{}.login) as unique_user_count
| convert ctime(lt) as start_time
| convert ctime(ft) as end_time
| table start_time,end_time,unique_user_count
| append
[ search index=okta earliest=-45d@d latest="12/15/2018:24:00:00" 
| stats min(_time) as lt max(_time) as ft dc(targets{}.login) as unique_user_count
| convert ctime(lt) as start_time
| convert ctime(ft) as end_time
| table start_time,end_time,unique_user_count
]

1. I'm trying to avoid hardcode latest time.
2. earliest=-45d@d does not calculate the correct date from latest="1/15/2019:24:00:00". it's showing Dec7 instead of Dec2
3. start_time duplicated data from first row

Hello,
- You could use tokens for the latest time if you want to add this in a dashboard
- You could refer to this documentation for snapping the time https://docs.splunk.com/Documentation/Splunk/7.2.3/SearchReference/SearchTimeModifiers
- Could you please elaborate a bit more on this problem?
