How the calculator counts

Both dates are included: 2 to 6 November is five calendar days.
Weekends are Saturday and Sunday. Public holidays follow article 112 of the Russian Labour Code, and moved days off follow the Government decree for each year.
When a holiday falls on a weekend, the decree for that year decides where the day off moves — the calculator takes the dates straight from it.
A working day before a holiday is one hour shorter, and the hours reflect it.
Hours: 8 a day on a 40-hour week, 7.2 on a 36-hour week, 4.8 on a 24-hour week.
“Date N working days ahead” counts from the next day: 1 is the first working day after the start date, and 0 is the start date itself.

The calendar inside a project plan

In Etapero the same production calendar is built into the schedule: work durations are set in working days, dates are recalculated from dependencies with holidays and moved days off. Shared Russian and Chinese calendars are available, a combined one included, along with a team leave schedule.
