Can I assume that your DH is also worrying about managing his time around housework, cooking etc? And if not, why not?
This isn't 1950, and housework, childcare, cooking, life admin are not women's jobs. They are jobs for any adults living in the house. Please tell me you don't have a sexist pig of a husband, who thinks that because he has a penis housework isn't his job??!! I'm decades older than you, and it wouldn't occur to my DH not to share chores equally.
The only time that the division of chores should be unequal is if one partner is doing less paid work than the other. So if one of you works 40 hours, and one works 30 hours, the PT worker can expect to do an additional 10 hours of work in the home. The outcome should be that you both get the same amount of 'down' time (for hobbies / socialising / resting).
Housework is not your job. If your DH does housework he is not helping you. It is an equal job, that belongs to both of you.
In aswer to your question, me and DH work the same hours in our paid work, so we simply divide up the house and garden jobs equally. In the week when we're working, it's mostly about cooking / pots / keeping things basically tidy / putting a wash in / doing the foodshop. All equally shared.
Come the weekend, we look at the jobs list, and divide it up, deciding who does what. Ensuring we don't have a situation where one person is sat reading / out doing a hobby while the other spends a weekend working.
If your DH doesn't think housework is his job, you have a big problem.
