Add Bulgaria Working Days

Adds or subtracts Bulgaria authority-scope working days in exact coverage. Requires explicit mon_fri_planning; education-only holidays do not create general rest.

When to use

You need a deterministic Bulgaria working-day offset.

Do not use when: Bulgaria 2026 nationwide statutory holidays, observed non-attendance days and January 2 one-off rest over an explicitly selected Monday-Friday planning baseline. November 1 is education-only and does not add general rest. No personal, shift, school, employer, bank/exchange, optional religious-leave, payroll or legal-deadline schedule is computed. Future years and additional local/sector closures are unsupported.

Example user requests

Add or subtract Bulgaria working days around One-off euro transition rest, not statutory holiday.
Add or subtract Bulgaria working days around May 24 Sunday replacement.
Add or subtract Bulgaria working days around No nationwide school-holiday substitute.

Formula

planning_workday = weekday AND no nationwide statutory/observed/one-off rest event

Apply 14 statutory dates, three observed non-attendance dates and January 2 one-off rest. Retain November 1 education-only annotation without adding general rest. Do not infer personal rosters.

FAQ

Is Monday-Friday mandatory for everyone?

No. Select mon_fri_planning explicitly. Articles 153 and 154a preserve roster and shift exceptions. Individual attendance and pay are not computed.

Do Easter weekends create extra substitute days?

No. Article 154(2) excludes Easter. April 14 remains a planning workday.

Is November 1 a rest day for all employees?

No. Its non-attendance scope is educational institutions. This general calendar records the annotation but does not invent a nationwide November 2 rest day.
