Add Estonia Working Days

Adds or subtracts Estonia authority-scope working days in exact coverage. Requires explicit mon_fri_planning; national-importance dates and three-hour shortening never add full-day rest.

When to use

You need a deterministic Estonia working-day offset.

Do not use when: Estonia 2026 statutory rest facts over an explicitly selected Monday-Friday planning baseline. Sixteen national-importance dates do not add rest. Four dates carry a conditional three-hour shortening rule but still count as one planning working date, not a half-day or full-day holiday. No substitute or bridge is invented. Individual shifts, actual working hours, opening hours, employer/local/sector/school/bank schedules, replacement weekly rest, payroll, legal deadlines and future years are not computed.

Example user requests

Add or subtract Estonia working days around Independence Day is statutory rest.
Add or subtract Estonia working days around Shortened working date is not full-day rest.
Add or subtract Estonia working days around National importance does not imply rest.

Formula

planning_workday = weekday AND no statutory_full_day_rest_event; shortened working dates count once

Apply 12 statutory rest dates; retain 16 non-rest observances and four conditional shortened dates separately. No personal hours or payroll inference.

FAQ

Are all named dates days off?

No. PTS sections 1-2 supply 12 statutory rest dates; section 3 supplies 16 separate national-importance dates without extra rest.

Does shortening make a half-day holiday?

No. The three-hour rule applies immediately before four named holidays when scheduled to work; a date counts once here, without an assumed eight-hour day or employee-hours/payroll calculation.

Are Easter Monday and Whit Monday holidays?

Neither is in PTS sections 1-2. April 6 and May 25 remain working dates in the selected 2026 Monday-Friday planning model.

Is this my attendance roster?

No. Required mon_fri_planning is an explicit planning model; shifts, actual opening hours, payroll and legal deadlines need other evidence.
