Can I change the calendars start day?



I'm in the US and our weeks start on sunday. The calendars for selecting maintenance, report windows, logs and so forth are starting with Monday. Can you please tell me how to change this? There doesn't seem to be a setting for that?

There is no setting for that in the PRTG GUI. But you can modify a javascript file inside PRTG. Simply open the file _Prtg.DateTimePicker.js in an editor of your choice. It resides in the following folder: C:\Program Files (x86)\PRTG Network Monitor\webroot\javascript Search for firstDay:1 and change it to firstDay:0

Of course you can use any other day of the week as well:

  • 0 - Sunday
  • 1 - Monday
  • 2 - Tuesday
  • 3 - Wednesday
  • 4 - Thursday
  • 5 - Friday
  • 6 - Saturday

Please note

This setting is not officially supported and you'll have to do these steps every time PRTG gets updated.

I was preparing to raise this very calendar-date-picker display issue when I found this entry. Though this was posted some time ago, I firmly support this feature request. I do, however, appreciate the manual override described here.

Having the option to select which day "starts the week" in Setup > Account Settings > My Account > Web Interface settings in the same vein as the Date Format customizations already available would be a boon to USers (and others to whom this format is common) not to mention a reduction in translation errors for the visual-minded. It is always a tiny chore to adjust against the offset positions in the current, Monday-first visualization.

Welp, I was not really aware of that workaround anymore - sorry! I sure would've provided you with that one :) I'll create a corresponding feature request and link it here.
