Flexible days vs. block days

Learn the difference between flexible and block vacation ranges, when each type applies, and how the Friday rule affects date selection.

Each 30-day vacation period is divided into two distinct types of days. The type is determined automatically by the number of days in the requested range — you do not choose it manually.

Overview

Flexible days

Flexible days are designed for short breaks throughout the year. An employee can use up to 7 flexible days per period, spread across one or more ranges.

• Minimum range length: 1 day
• Maximum range length: 7 consecutive days
• Total available per period: 7 days
• Stored on the schedule as diasFlexiblesDisponibles: 7

Once all 7 flexible days have been used, any remaining ranges must be taken as block days (minimum 7 consecutive days).

Flexible days are ideal for long weekends, personal appointments, or one-off days off. They can be taken as a single day at a time.

Block days

Block days are designed for the main vacation. A block range must span at least 7 consecutive days.

• Minimum range length: 7 consecutive days
• No maximum (up to remaining block balance)
• Total available per period: 23 days
• Stored on the schedule as diasBloqueDisponibles: 23

Block days are best planned well in advance. A common pattern is one 14-day block and one 9-day block.

How the type is assigned

The system inspects the number of days in a submitted range and assigns the type automatically:

days ≤ 7 AND flexible balance remaining  →  tipo: "flexible"
days > 7  OR  flexible balance exhausted  →  tipo: "bloque"

This logic lives in RegistroVacaciones.tsx (esFlexible flag at line 248) and is enforced again in validarRangoVacaciones in vacationUtils.ts.

Validation rules

The system prevents invalid requests with these checks:

• You cannot start a range on a Saturday or Sunday.
• If your flexible balance is 0, ranges of 7 days or fewer are blocked with an error.
• If a requested range exceeds the remaining balance for its type, the request is rejected.
• Ranges cannot overlap with already-scheduled ranges in the same period.

The Friday rule

When you select a Friday as the start date or end date of a range, the system automatically extends the end date to the following Sunday. The extra two days (Saturday and Sunday) are included in the diasSolicitados count, and the range is flagged with incluye_finde: true.

This behaviour is enforced in two places:

• calcularDiasConFinDeSemana in vacationUtils.ts — sets incluye_finde: true when either boundary is a Friday.
• RegistroVacaciones.tsx — watches the date inputs and automatically updates fechaFin to the Sunday when a Friday is selected, showing a toast notification.

The two weekend days count against the employee’s vacation balance. A range from Friday to Sunday costs 3 days, not 1.

Ranges that triggered the Friday rule are displayed with an “Incluye fin de semana” badge in the scheduled ranges list.

Example

An employee takes the following ranges during their "2025-2026" period:

Date range	Days	Type	Notes
3–4 March 2026	2	Flexible	Long weekend
7–21 July 2026	14	Block	Main summer vacation
14–23 September 2026	9	Block	Second block

Totals used: 2 flexible + 23 block = 25 days
Remaining: 5 flexible + 0 block = 5 days

Once block days are exhausted, any remaining flexible days can still be used in ranges of up to 7 days. However, once flexible days are exhausted, all remaining days must be taken in blocks of at least 7 consecutive days.
