What is the cron expression for every day at 10am?

The cron expression for every day at 10am is "0 10 * * *". Runs once a day at 10am, every day.

What should I watch out for when running a cron job every day at 10am?

10am runs collide head-on with peak production traffic. This is often the daily high-water mark for app load, so any non-trivial job here steals CPU and DB connections from real users. If it must run at 10, cap its resource use (a connection-pool limit, nice/ionice) and keep it short — overnight is for anything heavy. Time-zone math quietly breaks the "mid-morning" intent. A 0 10 * * * job on a UTC host fires at 2am US-Pacific and 7:30pm in India — the entire reason you chose 10am (peak attention) is lost. Pin CRON_TZ= to the target audience, or schedule separate per-region runs; never assume the server clock matches your readers.

Cron expression for Every day at 10am

0 10 * * *

Runs once a day at 10am, every day.

Next 5 runs (your local time)

These are shown in your browser’s timezone. The job itself runs in the scheduler’s timezone — often UTC — so the real run time can differ.

What people actually schedule with `0 10 * * *`

Posting social content at the mid-morning engagement peak, after the early-inbox triage has cleared
Sending follow-up or transactional reminders timed for when people are settled and actually reading
Mid-morning data refreshes that incorporate the first few hours of the day's activity

Use `0 10 * * *` on your platform

It’s the same 5-field expression everywhere — what changes is where you put it and which timezone it runs in.

Linux / crontab

0 10 * * * /path/to/your-command

Runs in the server’s local timezone — check it with timedatectl. Full field reference: crontab(5) man page.

GitHub Actions

on:
  schedule:
    - cron: "0 10 * * *"

GitHub Actions always runs scheduled jobs in UTC — there is no timezone setting, and runs can be delayed under load (official docs).

Kubernetes CronJob

spec:
  schedule: "0 10 * * *"

Defaults to UTC. Set spec.timeZone (Kubernetes 1.27+) for a specific zone — see the CronJob docs.

Quartz / Spring `@Scheduled`

Quartz uses 6 fields (seconds first): 0 0 10 * * *. Watch out: Quartz day-of-week is 1=SUN … 7=SAT (not 0–6), and day-of-month / day-of-week use ? — double-check if your schedule touches those fields (Quartz cron reference).

Daily 10am sends ignore the weekend cliff. Engagement for work content drops sharply Saturday/Sunday, so "every day" wastes two of seven posts. Use 0 10 * * 1-5 for weekday-only, and remember that in cron's day-of-week field both 0 and 7 mean Sunday, a classic off-by-one source.

Will you know if this job silently fails?

Cron jobs fail quietly — a server reboots, a path changes, or an error code is ignored — and nobody notices until the data is missing. A cron monitor (a dead-man’s-switch) alerts you when a scheduled job does not check in on time.

Is `0 10 * * *` the right schedule?

If the goal is the workday attention peak without weekend waste, every weekday at 9am is the tighter target. For genuinely heavy data jobs that don't need a specific viewing time, move the compute to an overnight slot like 3am and leave only the publish at 10.
