Android Question Correct day of week calculation (starting monday)

[peacemaker]

HI, All

Any help with piece of code to calculate normally the current week day starting the monday ?

DateTime.GetDayOfWeek(DateTime.Now)    'returns 1 for the Sunday, but need to calculate it as 7

AHLocale lib can give FirstDayOfWeek where the monday is 2.
How to calculate these all to Sunday =7 and Monday =1 ?

What exactly are looking for? You can get the day's name with DateUtils.GetDayOfWeekName.

User's settings of various days of week: say, working days in the schedule. The interface checkboxes are fixed for the sequence from Mon. to Sun., so recalculation is required.

Untested code:

Dim d As Int = DateTime.GetDayOfWeek(DateTime.Now) - 1
Dim offset As Int = AHLocale.FirstDayOFWeek - 1
Return ((d + 7 - offset) Mod 7) + 1
