A working-time calendar is not just an HR reference. Payroll uses it to test hourly minimum pay, convert a monthly wage when an employee is absent, and identify over- or undertime at the end of a summarised-working-time period. One overlooked public holiday or shortened day can shift all three results.
In more than 15 years of Estonian accounting, I have found that the safest approach is to lock the annual baseline before managers start building shifts. This guide gives the 2027 month-by-month norm for an ordinary full-time Monday-to-Friday schedule, then shows how to adapt it for part-time work, absences and shift schedules. The annual table is a baseline, not a substitute for the employment contract or the employee's actual roster.
Calculate the calendar baseline before using payroll data
Under Estonian Employment Contracts Act, sections 43–44 and 53, full-time work is presumed to be 40 hours in a seven-day period and eight hours a day unless shorter working time is agreed. Tööelu guidance on working time and monthly norms turns that rule into a monthly calculation: count Monday-to-Friday working days, exclude public holidays, multiply by eight, and subtract the statutory three-hour reductions.
The formula describes the common five-day pattern. It does not mean that every employee must work those exact hours in each calendar month. A part-time agreement, summarised working time, an approved roster or an absence changes the employee-specific figure, while the calendar norm remains the control starting point.
| Calculation step | 2027 treatment | Payroll evidence |
|---|---|---|
| Weekdays | Count Monday to Friday | Calendar |
| Public holidays | Remove holidays falling on weekdays | Official holiday list |
| Shortened days | Subtract three hours when applicable | Roster and working-time record |
| Employee adjustment | Apply workload and absences | Contract, roster and absence data |
Use the 2027 monthly working-hours table
The dates come from the Estonian Public and National Holidays Act. For the standard five-day pattern, Good Friday on 26 March and Restoration of Independence Day on 20 August reduce the norm, while Spring Day and Pentecost fall at weekends and do not remove another weekday.
The table already deducts three hours on 23 February, 22 June, 23 December and 31 December. It totals 2,020 hours for 2027. Use the monthly row in the payroll workpaper, but keep the assumptions visible so a reviewer can distinguish the calendar baseline from an employee-specific norm.
| Month | Working days | Full-time hours | Holiday or reduction affecting the norm |
|---|---|---|---|
| January | 20 | 160 | 1 January |
| February | 19 | 149 | 24 February; 23 February −3 h |
| March | 22 | 176 | 26 March |
| April | 22 | 176 | — |
| May | 21 | 168 | 1 and 16 May fall at weekends |
| June | 20 | 157 | 23–24 June; 22 June −3 h |
| July | 22 | 176 | — |
| August | 21 | 168 | 20 August |
| September | 22 | 176 | — |
| October | 21 | 168 | — |
| November | 22 | 176 | — |
| December | 22 | 170 | 24 December; 23 and 31 December −3 h |
| 2027 total | 254 | 2,020 | Four shortened working days |
Do not prorate the three-hour holiday reduction
The working day immediately before New Year's Day, Independence Day, Victory Day and Christmas Eve is shortened by three hours. In 2027 the affected dates are 23 February, 22 June, 23 December and 31 December. The day before Good Friday and the day before Restoration of Independence Day are not on that statutory list.
The reduction is not automatically halved for a 0.5 workload. If a person normally works four hours on the affected day, the scheduled day becomes one hour. If only two hours were due, those two hours are removed; the norm cannot become negative. If operations require the unreduced shift, agree it with the employee and handle the extra time under the working-time rules.
| Pattern | February 2027 | June 2027 | December 2027 | Annual total |
|---|---|---|---|---|
| Full-time, 8 h Monday–Friday | 149 h | 157 h | 170 h | 2,020 h |
| Fixed 4 h Monday–Friday | 73 h | 77 h | 82 h | 1,004 h |
| Why not exactly 50%? | Full −3 h | Full −3 h | Two × −3 h | Reduction is not prorated |
Adjust absences from the roster that actually applied
When a roster already exists, reduce the employee's norm by the scheduled hours missed because of holiday leave, sickness or another qualifying absence. Do not subtract hours for rostered days off inside the same absence period. Otherwise a shift employee can acquire artificial overtime merely because the absence covered calendar days on which no work was planned.
If no roster has been prepared, Tööelu uses the employee's calculated daily workload for calendar working days inside the absence. For a fixed 0.5 workload normally spread as four hours Monday to Friday, five absent weekdays ordinarily reduce the norm by 20 hours, subject to any holiday or shortened-day effect within those dates.
- Save the employment agreement and workload valid for the month.
- Retain the roster version that existed before the absence.
- Mark the exact scheduled hours covered by each absence.
- Reconcile adjusted norm, actual hours and payroll result together.
Separate the calendar norm from pay and overtime conclusions
According to Tööelu guidance on wages and standard hours, an hourly-paid employee is paid for hours worked, while minimum-pay checks use the applicable statutory rate and standard hours. Do not insert a 2026 hourly rate into the 2027 calendar: confirm the rate in force for the payment period after the Government has set it.
For a monthly-paid employee under summarised working time, a long or short calendar month does not by itself change the agreed monthly wage. Overtime and undertime are assessed at the end of the agreed accounting period after absences and roster changes have been handled correctly. Store calendar norm, adjusted employee norm, actual hours and compensated hours as separate fields.
I ask payroll to preserve both numbers: the untouched calendar norm and the adjusted employee norm. If one cell is overwritten, nobody can later tell whether the difference came from a holiday, workload, absence or a manual correction.
Estonia's 2027 working-time calendar gives payroll a 2,020-hour full-time baseline. The correct employee result comes only after workload, shortened days, the applicable roster and absences are added without overwriting that baseline.
