A tour of the Calendar tab: days off, half days and fixing the past

Themes: App feature9 November 2026·4 min read·By David Lawrence

Most people open Clockflux to check in and check out, and never spend long on the Calendar tab. It's where you fix the day you forgot to track, book a week away in one go, and see how a month adds up. This post goes through it, along with the few rules that decide how a change here shows up in your totals.

The month at a glance

The tab shows one month at a time. Each day shows what happened on it:

• a dot when you logged hours;
• an emoji badge when it's a day off, or a 🛋️ when it falls in your weekend;
• a ⚠ when Clockflux checked you out automatically, with a note asking you to verify the hours.

On a computer, hover over a day with hours to see its total and how many sessions it holds. On the right of each row, the week column adds up the week's hours against its target, with a bar that fills as you get there. The target already has your days off taken out.

On the free plan the calendar covers the current year. Clockflux Pro opens up past and future years, and adds an Export… button for any date range, as CSV, PDF or a calendar file.

Fixing a past day

Tap any day to open it. The sessions are listed with their check-in and check-out times, and you can change a time, delete a session or add one. A few things worth knowing:

• A day with nothing in it opens with two sessions already filled in, 08:00 to 12:00 and 13:00 to 17:00. Adjust them to what you really did, and save.
• A night shift works. If the check-out time is earlier than the check-in, Clockflux reads it as the next morning and marks the row "+1d", with the resulting duration beside it, so a typo shows up straight away.
• Mistakes are caught before saving. You'll get a message if a session overlaps another, if a check-out has no check-in, or if more than one session is left running, or the running one isn't the last of the day.

The same editor is where you change what kind of day it was, which is the next part.

Marking a day off

At the top of the editor are the four kinds of day off:

• Personal 🌴, for your holiday. It's the only kind that comes out of your holiday balance.
• Sick 🤒
• Official, for a public holiday. It shows a flag, Swiss by default, and Pro lets you pick another.
• Unpaid 💸

All four take the day out of your weekly target, so a week with a day off isn't judged as a short week. A full day off removes 8 hours from the target, and you can't edit its sessions. A weekend day is the same, and shows as a fixed "Weekend" label instead of the picker. Tapping the active type again clears it.

Half days

Personal, sick and unpaid days can be a half day. Switch on ½ Half day after choosing the type. The target for that day drops by half, 4 hours instead of 8, and you're expected to work the rest, so the sessions stay editable. A half personal day uses 0.5 days of your holiday allowance. Public holidays are always whole days.

Several days at once

For a week away, opening each day gets tedious. Press Select above the calendar instead, then:

1. Tap each day you want. Weekend days can't be selected, so they don't use up your allowance.
2. Pick the type in the bar that appears. Turn on ½ Half day first if you want the half-day version.
3. The selected days are all marked and you're back in the normal view.

Clear in the same bar removes the day-off marker from the selected days. Export is switched off while you're selecting.

What a day off changes

Three things move when you mark a day off:

• The weekly target goes down by that day's share, in the calendar's week column and on the Health tab.
• Your holiday balance goes down only for personal days. Planned days that are still in the future show as planned until their date arrives.
• Hours logged on a full day off stop counting in your totals. If you worked on a weekend day, those hours won't add to your overtime.

That last point matters for one habit. If you want to take back a day of overtime, leave it as an ordinary workday and don't check in. A day off lowers the target instead of spending your balance.

Your weekend

By default, Saturday and Sunday are the weekend. If you work another pattern, such as Sunday to Thursday or a four-day week, set it in Settings → Weekend. It's free. The setting applies to your whole history, so past weeks are recalculated too, and hours logged on a day that now counts as off stop counting in past totals and in your overtime balance.
