In views, filters on date based on a current period are in fact based on the first day of the current period.

Steps to reproduce

1. Create a table with a date column.
2. Create five lines:

• one with date in past month,
• one at first day of current month,
• one in middle of current month,
• one at last day of current month;,
• one in next month.

3. Create a view.
4. Apply filters on the date column with condition "superior to", "superior or equal to, "inferior to" then "inferior or equal to".

Expected behavior

• When filtering date as "superior to" current month, no line where the date is in the current month shall be visible, only lines where the date is in following months.
• When filtering date as "superior or equal to" current month, every line where the date is in the current and following months shall be visible.
• When filtering date as "inferior to" current month, no line where the date is in the current month shall be visible, only lines where the date is in previous months.
• When filtering date as "inferior or equal to" current month, every line where the date is in the previous and current months shall be visible.

Actual behavior

• When filtering date as "superior to" current month, lines where the date is superior or equal to the second day of the current month are visible.
• When filtering date as "superior or equal to" current month, every line where the date is in the current and following months are visible. As expected.
• When filtering date as "inferior to" current month, no line where the date is in the current month is be visible, only lines where the date is in previous months. As expected
• When filtering date as "inferior or equal to" current month, every line where the date is in previous months are visible and the line where the date is the first day of the current month. Lines where the date is in the current month but superior or equal to the first day of the current month are hidden.

Same issue has been reproduced with "current week", assuming that the first day of the week is Sunday.
Same issue has been reproduced with "current year".

To put it simply, the filter "current period" is in reality "first day of the current period", period being replaced by week, month or year.

Reproduce the issue in a view with date values spanning the current week, month, and year, then trace the date-filter entry point for current-period conditions. Verify the boundary behavior for strict and inclusive comparisons; done means dates throughout the current period are handled consistently with the expected results in the report.
